Issue #4688 : Add a heuristic so that tuples and dicts containing only
...
untrackable objects are not tracked by the garbage collector. This can
reduce the size of collections and therefore the garbage collection overhead
on long-running programs, depending on their particular use of datatypes.
(trivia: this makes the "binary_trees" benchmark from the Computer Language
Shootout 40% faster)

fix building the core with --disable-unicode

I changed some bytearray methods to use strings instead of unicode like bytes_repr
Also, bytearray.fromhex() can take strings as well as unicode

collecting the oldest generation) so that allocating lots of objects without
destroying them does not show quadratic performance. Based on a proposal by

Python 2.6 should stick with PyString_* in its codebase. The PyBytes_* names
in the spirit of 3.0 are available via a #define only. See the email thread.

Patch from Aldo Cortesi (OpenBSD buildbot owner).
...
After the patch (45590) to add extra debug stats to the gc module, Python
was crashing on OpenBSD due to:
Fatal Python error: Interpreter not initialized (version mismatch?)
This seems to occur due to calling collect() when initialized (in pythonrun.c)
is set to 0. Now, the import will occur in the init function which
shouldn't suffer this problem.

SF Patch #1463867 : Improved generator finalization to allow generators

that are suspended outside of any try/except/finally blocks to be
garbage collected even if they are part of a cycle. Generators that
suspend inside of an active try/except or try/finally block (including
those created by a ``with`` statement) are still not GC-able if they
are part of a cycle, however.
