  Modified files:
    sys/kern             kern_fork.c 
  Log:
  Prevent a race condition between fork1() and whatever changes the pgrp by
  setting the new process' p_pgrp again before inserting it in the p_pglist.
  Without it we can get the new process to be inserted in a different p_pglist
  than the one p2->p_pgrp points to, and this is not something we want to happen.
  This is not a fix, merely a bandaid, but it will work until someone finds a
  better way to do it.
