Modified files:
sys/kern tty.c tty_pty.c
Log:
- Lock proctree_lock instead of pgrpsess_lock.
- Use temporary variables to hold a pointer to a pgrp while we dink with it
while not holding either the associated proc lock or proctree_lock. It
is in theory possible that p->p_pgrp could change out from under us.
