Guess again, bozo.  You've also got to check for p->p_pgrp clashes.
You can't have mpid == an active process group id.

Enough of this discussion.  Obviously 30000 was chosen as a "nice"
number that fits into a signed 16 bit int.  And, yes, I'm sure it's
not interesting modulo Jon Bon Jovi's short size.

Who cares about p->p_pid?  As long as it's unique and != any active pgrp.
