9aee99be16 Raise RuntimeError if the second argument to isinstance() or issubclass() 
is a tuple nested to a depth beyond the interpreter's recursion limit to
prevent a segfault from blowing the C stack.
Fixes bug #858016 .

acfe104847 PyFile_WriteObject(): some of the local variables are only used when 
Py_USING_UNICODE is defined

95e4f23b09 Fixed a bug in object.__reduce_ex__ (reduce_2) when using protocol 
2.  Failure to clear the error when attempts to get the __getstate__
  attribute fail caused intermittent errors and odd behavior.

d6ea07f9ac SF patch #875689: >100k alloc wasted on startup 
(Contributed by Mike Pall.)

Make sure fill_free_list() is called only once rather than 106 times
when pre-allocating small ints.

8c077f99d0 Backport checkin: 
Fix reallocation bug in unicode.translate(): The code was comparing
characters instead of character pointers to determine space requirements.

74788b6af4 Allocating a new weakref object can cause existing weakref objects for 
the same object to be collected by the cyclic GC support if they are
only referenced by a cycle.  If the weakref being collected was one of
the weakrefs without callbacks, some local variables for the
constructor became invalid and have to be re-computed.

The test caused a segfault under a debug build without the fix applied.

a7555f8413 Fix bug in interpretation of the "callback" argument in the constructors for 
weakref ref and proxy objects; None was not being treated as identical to
NULL, though it was documented as equivalent.

ca6919c180 SF bug 839548: Bug in type's GC handling causes segfaults. 
Also SF patch 843455.

This is a critical bugfix, backported from 2.4 development.
I don't intend to backport beyond 2.3 maint.  The bugs this fixes
have been there since weakrefs were introduced.

8e81b7efad subtype_dealloc(): A more complete fix for critical bug 840829 + 
expanded the test case with a piece that needs the more-complete fix.

I don't intend to backport this beyond 2.3 maint.  It's a critical
bugfix, and should be backported to 2.2, 2.1, ..., if more releases in
those lines get made.

695461f200 Backport of fix for SF bug 840829, memory corruption in some cases of 
weakref callbacks.

This is a critical bugfix.  It's already been fixed on the trunk (2.4
development).  I don't intend to backport it to the 22 line, but if a
2.2.4 ever gets released, this should be in it.

218f9abe45 Backport checkin: 
Fix a bug in the memory reallocation code of PyUnicode_TranslateCharmap().
charmaptranslate_makespace() allocates more memory than required for the
next replacement but didn't remember that fact, so memory size was growing
exponentially every time a replacement string is longer that one character.
This fixes SF bug #828737.

6b560bc648 SF patch #820195: make object.__contains__() returns True or False instead 
of 1 or 0.

Backport Guido's fix to the default __contains__() and to proxy_has_key()
so they will properly return booleans instead of integers.
