+A. HISTORY OF THE SOFTWARE
+==========================
+
+Python was created in the early 1990s by Guido van Rossum at Stichting
+Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
+as a successor of a language called ABC.  Guido remains Python's
+principal author, although it includes many contributions from others.
+
+In 1995, Guido continued his work on Python at the Corporation for
+National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
+in Reston, Virginia where he released several versions of the
+software.
+
+In May 2000, Guido and the Python core development team moved to
+BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
+year, the PythonLabs team moved to Digital Creations, which became
+Zope Corporation.  In 2001, the Python Software Foundation (PSF, see
+https://www.python.org/psf/) was formed, a non-profit organization
+created specifically to own Python-related Intellectual Property.
+Zope Corporation was a sponsoring member of the PSF.
+
+All Python releases are Open Source (see http://www.opensource.org for
+the Open Source Definition).  Historically, most, but not all, Python
+releases have also been GPL-compatible; the table below summarizes
+the various releases.
+

+                    from                                compatible? (1)

+    2.2 and above   2.1.1       2001-now    PSF         yes
+
+Footnotes:
+
+(1) GPL-compatible doesn't mean that we're distributing Python under
+    the GPL.  All Python licenses, unlike the GPL, let you distribute
+    a modified version without making your changes open source.  The
+    GPL-compatible licenses make it possible to combine Python with
+    other software that is released under the GPL; the others don't.
+
+(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
+    because its license has a choice of law clause.  According to
+    CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
+    is "not incompatible" with the GPL.
+
+Thanks to the many outside volunteers who have worked under Guido's
+direction to make these releases possible.

+   * "last chance" anti-recursion protection is triggered when the recursion
+     level exceeds "current recursion limit + 50". By construction, this

+     means the cleanup code has itself gone into an infinite loop, or the
+     RecursionError has been mistakingly ignored. When this protection is
+     triggered, the interpreter aborts with a Fatal Error.
+

+   recursion level drops below "current recursion limit - 50". This heuristic
+   is meant to ensure that the normal anti-recursion protection doesn't get

+

+/* Trashcan mechanism, thanks to Christian Tismer.
+
+When deallocating a container object, it's possible to trigger an unbounded
+chain of deallocations, as each Py_DECREF in turn drops the refcount on "the
+next" object in the chain to 0.  This can easily lead to stack overflows,
+especially in threads (which typically have less stack space to work with).
+
+A container object can avoid this by bracketing the body of its tp_dealloc
+function with a pair of macros:
+
+static void
+mytype_dealloc(mytype *p)
+{
+    ... declarations go here ...
+
+    PyObject_GC_UnTrack(p);        // must untrack first
+    Py_TRASHCAN_BEGIN(p, mytype_dealloc)
+    ... The body of the deallocator goes here, including all calls ...
+    ... to Py_DECREF on contained objects.                         ...
+    Py_TRASHCAN_END                // there should be no code after this
+}
+
+CAUTION:  Never return from the middle of the body!  If the body needs to
+"get out early", put a label immediately before the Py_TRASHCAN_END
+call, and goto it.  Else the call-depth counter (see below) will stay
+above 0 forever, and the trashcan will never get emptied.
+
+How it works:  The BEGIN macro increments a call-depth counter.  So long
+as this counter is small, the body of the deallocator is run directly without
+further ado.  But if the counter gets large, it instead adds p to a list of
+objects to be deallocated later, skips the body of the deallocator, and
+resumes execution after the END macro.  The tp_dealloc routine then returns
+without deallocating anything (and so unbounded call-stack depth is avoided).
+
+When the call stack finishes unwinding again, code generated by the END macro
+notices this, and calls another routine to deallocate all the objects that
+may have been added to the list of deferred deallocations.  In effect, a
+chain of N deallocations is broken into (N-1)/(PyTrash_UNWIND_LEVEL-1) pieces,
+with the call stack never exceeding a depth of PyTrash_UNWIND_LEVEL.
+
+Since the tp_dealloc of a subclass typically calls the tp_dealloc of the base
+class, we need to ensure that the trashcan is only triggered on the tp_dealloc
+of the actual class being deallocated. Otherwise we might end up with a
+partially-deallocated object. To check this, the tp_dealloc function must be
+passed as second argument to Py_TRASHCAN_BEGIN().

+   NOTE: about untracking of mutable objects.
+
+   Certain types of container cannot participate in a reference cycle, and
+   so do not need to be tracked by the garbage collector. Untracking these
+   objects reduces the cost of garbage collections. However, determining
+   which objects may be untracked is not free, and the costs must be
+   weighed against the benefits for garbage collection.
+
+   There are two possible strategies for when to untrack a container:
+
+   i) When the container is created.
+   ii) When the container is examined by the garbage collector.
+
+   Tuples containing only immutable objects (integers, strings etc, and
+   recursively, tuples of immutable objects) do not need to be tracked.
+   The interpreter creates a large number of tuples, many of which will
+   not survive until garbage collection. It is therefore not worthwhile
+   to untrack eligible tuples at creation time.
+
+   Instead, all tuples except the empty tuple are tracked when created.
+   During garbage collection it is determined whether any surviving tuples
+   can be untracked. A tuple can be untracked if all of its contents are
+   already not tracked. Tuples are examined for untracking in all garbage
+   collection cycles. It may take more than one cycle to untrack a tuple.
+
+   Dictionaries containing only immutable objects also do not need to be
+   tracked. Dictionaries are untracked when created. If a tracked item is
+   inserted into a dictionary (either as a key or value), the dictionary
+   becomes tracked. During a full garbage collection (all generations),
+   the collector will untrack any dictionaries whose contents are not
+   tracked.
+
+   The module provides the python function is_tracked(obj), which returns
+   the CURRENT tracking status of the object. Subsequent garbage
+   collections may change the tracking status of the object.
+
+   Untracking of certain containers was introduced in issue #4688, and
+   the algorithm was refined in response to issue #14775.
