You can do that in Python, basically you need to check some envvars to
get the file descriptor number then use os.fdopen() to use those
integers as python file objects... or use os.write()/os.read() that
maps directly to C calls. I'm pretty sure there are similar things for
sockets/sendmsg/readmsg.
