Log Message:
Py_Finalize():  disabled the second call of cyclic gc, and added extensive
comments about why both calls to cyclic gc here can cause problems.

Already fixed on the trunk.  Since the calls were introduced in 2.3,
that's the end of it.

    This has been repaired.
  
+ - At Python shutdown time (Py_Finalize()), 2.3 called cyclic garbage
+   collection twice, both before and after tearing down modules.  The
+   call after tearing down modules has been disabled, because too much
+   of Python has been torn down then for __del__ methods and weakref
+   callbacks to execute sanely.  The most common symptom was a sequence
+   of uninformative messages on stderr when Python shut down, produced
+   by threads trying to raise exceptions, but unable to report the nature
+   of their problems because too much of the sys module had already been
+   destroyed.
+ 
  - Patch #820195: object.__contains__() now returns True or False instead
    of 1 or 0.
