When you've done a "restart" are there any of the old smbd
processes left around ? If not, then you are incorrect, and
a kill -9 does terminate them.

If you can pick a process id and kill -9 it and it doesn't
die, then you have a kernel bug or hardware issue. That's
"the rules" :-).

No, smbd should go away once the client has disconnected
(all calls on the socket will return -1 and smbd will
terminate itself).
