  Log:
  From the submitter:
  
    - this causes POSIX locking to use the thread group leader
     (p->p_leader) as the locking thread for all advisory locks.
     In non-kernel-threaded code p->p_leader == p, so this will have
     no effect.
  
     This results in (more) correct POSIX threaded flock-ing semantics.
  
     It also prevents the leader from exiting before any of the children.
     (so that p->p_leader will never be stale) in exit1().
  
     We have been running this patch for over a month now in our lab
     under load and at customer sites.
