Uh... maybe?  I think I just got out of my depth here... is Python
compiled specially for cygwin, or is it the standard Windows Python
that is involved?

If the latter, which I now doubt for some reason, then yes, os.kill()
can kill things spawn with spawnl/v/p/whatever provided that you use
the fake os.kill that I provided before, because os.kill doesn't
normally exist on Windows.
