This patch make subprocess.Popen support file-like
objects without fileno for stdout and stderr on Windows
(intend to do Unix once patch accepted). It makes
subprocess.Popen able to redirect stdout and stderr to
objects like StringIO or other objects with file
objects interface.

Bug/feature request 1260171 addresses the same basic issue,
but with the idea of a method like Popen.communicate() that
writes and reads directly to/from file-like objects, instead
of reading and returning strings.
http://sourceforge.net/tracker/index.php?func=detail&aid=1260171&group_id=5470&atid=105470

But having submitted that other request, I have no real
opinion of one technique over the other, except that one of
them would be really nice to have.

I believe this should be closed as the patch refers to various win32xxx imports that no longer exists in subprocess.py.
