* bpo-27448: Work around a gc.disable race condition in subprocess.
This works around a gc.isenabled/gc.disable race condition in the 2.7
subprocess module by using a lock for the critical section. It'll
prevent multiple simultaneous subprocess launches from winding up with
gc remaining disabled but it can't fix the ultimate problem: gc enable
and disable is a global setting and a hack.
Users are *strongly encouraged* to use subprocess32 from PyPI instead
of the 2.7 standard library subprocess module. Mixing threads with
subprocess is a recipie for disaster otherwise even with "fixes" to
ameliorate common issues like this.
* Add a blurb!
On Windows, subprocess.Popen.communicate() now also ignore EINVAL
on stdin.write() if the child process is still running but closed the
pipe.
(cherry picked from commit d52aa31378)
"ValueError: insecure string pickle" exception instead of the actual exception
on some platforms such as Mac OS X when an exception raised in the forked child
process prior to the exec() was large enough that it overflowed the internal
errpipe_read pipe buffer.

Fix#8956. ValueError message was only mentioning one signal.
Rather than list out the three signals (or more over time), the message was
made less specific but still descriptive.

interpreter shutdown semantics. Same issue goes for the methods that __del__
called. Now all the methods capture the global objects it needs as default
values to private parameters (could have stuck them on the class object itself,
but since the objects have nothing directly to do with the class that seemed
wrong).
There is no test as making one that works is hard. This patch was
verified against a consistently failing test in Mercurial's test suite, though,
so it has been tested in some regard.
Closes issue #5099. Thanks to Mary Stern for the bug report and Gabriel
Genellina for writing another patch for the same issue and attempting to write
a test.
by default as well. This change fixes that by treating -Q like -3 when it comes
to DeprecationWarning; using it causes the silencing to not occur.
Fixes issue #7319.
Since CREATE_NEW_* are used for the creation flags of a subprocess, they
were added to __all__. The rest of the previously exposed attributes are
now qualified by _subprocess.ATTR rather than importing *.
os.kill takes one of two newly added signals, CTRL_C_EVENT and
CTRL_BREAK_EVENT, or any integer value. The events are a special case
which work with subprocess console applications which implement a
special console control handler. Any other value but those two will
cause os.kill to use TerminateProcess, outright killing the process.
This change adds win_console_handler.py, which is a script to implement
SetConsoleCtrlHandler and applicable handler function, using ctypes.
subprocess also gets another attribute which is a necessary flag to
creationflags in Popen in order to send the CTRL events.
