You are being neither (I think). This amounts to the same suggestion
that Charles made and which I think would be a good solution.
Ie. for a mount type like snfs where the mount_snfs process will dag
around actually doing some magic, it could put its PID in the mount
umount would then simply need to _know_ that if PID is set, the right
thing for it to do is just KILL that PID. Rather than what it
currently does "oh NFS I know what to do about that...".
