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.

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.

Fixes Issue #16114 : The subprocess module no longer provides a
...
misleading error message stating that args[0] did not exist when
either the cwd or executable keyword arguments specified a path that
did not exist.
It now keeps track of if the child got as far as preexec and reports it if
not back to the parent via a special "noexec" error message value in
the error pipe so that the cwd can be blamed for a failed chdir
instead of the exec of the executable being blamed instead.
The executable is also always reported accurately when exec fails.
Unittests enhanced to cover these cases.

issue7213 + issue2320: Cause a DeprecationWarning if the close_fds argument is

not passed to subprocess.Popen as the default value will be changing in a
future Python to the safer and more often desired value of True.
DeprecationWarnings that show up in a lot of existing code are controversial
and have caused pain in the past. I'd like to leave this on for 3.2 beta1 and
see how things go. We can remove the warning if it is deemed too noisy during
any betas. (case study: the md5 and sha module DeprecationWarnings are loathed
around the world as those modules were never going to be removed in 2.x and
2to3 has a fixer for code that uses them)
