I checked, and, for windows platform subprocess.py uses the modules
mvscrt and _subprocess, which I ham unable to
locate on my windows XP python 2.6 installation. This make the whole
thing harder, even impossible if _subprocess has
been created especially for subprocess.py.

For non-windows platform, subprocess.py seem to use only fairly well-
established module, so there is a chance to backport it.
