ok.

that's what it's supposed to do, at least ;-)

the popen2 module now assumes that if the os module exports a
popen2 function, it returns the file descriptors in a "sane" order.
(same goes for popen3 and popen4, of course).

definitely.  I suggest moving the bulk of popen2.py to os.py (alternatively,
to a separate "posixpopen.py" module which is imported from os.py on
posix platforms).

the popen2 module itself is then reduced to a thin wrapper, and marked
as deprecated.

comments?
