This suggests that you believe the return value from os.spawnl() is
actually the PID.  Unfortunately that doesn't appear to be the case
on Windows.  See the note in the doc-string for my code sample from
the previous post (on Windows spawn* actually returns a "handle",
not the PID itself, and apparently turning the one into the other
is non-trivial).
