1f83866ecd Rename a local variable for readability and change a "this can't 
happen" print() call into a RuntimeWarning as it should've been in the
first place.  Because nothing should ever cause unexpected stdout output.

a10ddb8a55 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.

5591b02a4c 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.

of the subprocess module now kill the process, read its status (to avoid
zombis) and close pipes.

ab85ff3d1a Issue #12591: Improve support of "universal newlines" in the subprocess 
module: the piped streams can now be properly read from or written to.

(this was broken due to the 2.x to 3.x transition; communicate() support
is still sketchy)

59fd1bfcc1 The _posixsubprocess module is now required on POSIX. 
Remove the pure Python POSIX subprocess implementation.

If non-CPython VMs (are there any for 3.x yet?) were somehow depending
on this, they already have the exact same set of problems with Python
code being executed after os.fork() that _posixsubprocess was written
to deal with.  They should implement an equivalent outside of Python.
