72e7761301 issue12085: Use more Pythonic way to check _child_created. 
_active shouldn't be cached, it set to None on shutdown.

7b83b18679 Fixes issue #19929: Call os.read with 32768 within subprocess.Popen 
communicate rather than 4096 for efficiency.  A microbenchmark shows
Linux and OS X both using ~50% less cpu time this way.

016b9e38f7 Use a larger amount of data for tests such as the interrupted_write 
tests that depend on filling up an OS pipe so that they work properly
on systems configured with large pipe buffers.

Also a subprocess docstring update that i forgot was in my client when
i did the original 3.3 commit... easier to just leave that in here
with this one than go back and undo/redo.

445ad997ab Fix #14470. Remove w9xpopen per PEP 11. 
As stated in PEP 11, 3.4 removes code on Windows platforms where
COMSPEC points to command.com. The w9xpopen project in Visual Studio
was added to support that case, and there was a special case in subprocess
to cover that situation. This change removes the w9xpopen project from
the Visual Studio solution and removes any references to the w9xpopen
executable.

c2c4cb624b Fixes issue #16140: The subprocess module no longer double closes its 
child subprocess.PIPE parent file descriptors on child error prior to
exec().

This would lead to race conditions in multithreaded programs where
another thread opened a file reusing the fd which was then closed out
from beneath it by the errant second close.

d4b645ef42 Remove the subprocess "bad exception data" warning (formerly a print!) 
all together and just include the repr of the data in the exception
itself instead of the useless string "Unknown".

This code path is unlikely to even be possible to take given the
nature of the pipe it gets subprocess data from.
