c15c88c13d Issue #12494: Close pipes and kill process on error in subprocess functions 
On error, call(), check_call(), check_output() and getstatusoutput() functions
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.

2b228f0d9b Include the timeout value in TimeoutExpired. 
This was the original intention, but it wasn't threaded all the way through due
to 'endtime'.  Also added a trivial assertion to get coverage of __str__.

31aa7dd141 Add a 'timeout' argument to subprocess.Popen. 
If the timeout expires before the subprocess exits, the wait method and the
communicate method will raise a subprocess.TimeoutExpired exception.  When used
with communicate, it is possible to catch the exception, kill the process, and
retry the communicate and receive any output written to stdout or stderr.
