objects. (1) The comparison could incorrectly return True in some cases
(2**53+1 == complex(2**53) == 2**53), breaking transivity of equality.
(2) The comparison raised an OverflowError for large integers, leading
to unpredictable exceptions when combining integers and complex objects
in sets or dicts.

_PyUnicode_AsDefaultEncodedString() uses a magical PyUnicode attribute to
automatically destroy PyUnicode_EncodeUTF8() result when the unicode string is
destroyed.

http://code.google.com/p/data-race-test/wiki/ThreadSanitizer is a dynamic data
race detector that runs on top of valgrind. With this patch, the binaries at
http://code.google.com/p/data-race-test/wiki/ThreadSanitizer#Binaries pass many
but not all of the Python tests. All of regrtest still passes outside of tsan.
I've implemented part of the C1x atomic types so that we can explicitly mark
variables that are used across threads, and get defined behavior as compilers
advance.
I've added tsan's client header and implementation to the codebase in
dynamic_annotations.{h,c} (docs at
http://code.google.com/p/data-race-test/wiki/DynamicAnnotations).
Unfortunately, I haven't been able to get helgrind and drd to give sensible
error messages, even when I use their client annotations, so I'm not supporting
them.
This function is only used to decode Python module filenames, but Python
doesn't support surrogates in modules filenames yet. So nobody noticed this
minor bug.

Issue #8259: Get rid of 'outrageous left shift count' error when
left-shifting an integer by more than 2**31 on a 64-bit machine. Also
convert shift counts to a Py_ssize_t instead of a C long.

Use a more robust infinity check in _Py_HashDouble.
This fixes a test_decimal failure on FreeBSD 8.0. (modf apparently
doesn't follow C99 Annex F on FreeBSD.)

Fix the NEWS about my last commit: an unicode subclass can now override the
__unicode__ method (and not the __str__ method).
Simplify also the testcase.

Add support for weak references to code objects. This will be used by an optimization in the incoming Python 3 JIT.
Patch by Reid Kleckner!

POSIX systems with a C extension module. This is required in order for
the subprocess module to be made thread safe.
The pure python implementation is retained so that it can continue to be
used if for some reason the _posixsubprocess extension module is not
available.
The unittest executes tests on both code paths to guarantee compatibility.
* Moves PyLong_FromPid and PyLong_AsPid from posixmodule.c into longobject.h.
