Hm.  I'd much rather see a pure Python implementation.  This doesn't
seem to be something that's particularly performance critical.
Starting a process takes so many OS resources that the overhead of
doing it in Python is negligeable.

I expect only a very small number of win32all entry points to be
needed in order to implement popen5, and those we can implement in a
separate C module (just as we did for _winreg, which roughly
duplicates the registry access API from win32all).
