The subprocess module could probably do with a HOWTO, full stop.
Subprocess invocation is something where platform details are always
going to matter a lot, and there are subtle details even on Unix that
are confusing (e.g. I have a command in my current project that I've
only managed to get working by running it via the shell - I still
don't know why direct invocation of the binary with the appropriate
arguments doesn't work).

At the moment, we're still trying to cram an entire essay on
subprocess invocation into the subprocess.Popen constructor
definition, which is far from optimal.
