Actually as Chris *didn't* say, I was reading that wrong :-)

Anyway, I'd try deleting the handle.  AFAIK Python will run the
destructor immediately, and the path taken via guestfs_close certainly
kills the subprocess:

http://git.annexia.org/?p=libguestfs.git;a=blob;f=src/guestfs.c;h=8b7ab4d7713ccff93f6b9bf0a066970ce3c8e8bb;hb=HEAD#l169

If you're really worried about the subprocess staying around, then
grab the PID (g.get_pid) and kill the process *after* deleting the
handle.  (This is way outside the scope of the API ...)
