  Modified files:
    sys/miscfs/procfs    procfs_ctl.c 
  Log:
  Proc locking.  Lock around psignal() and also ensure both an exclusive
  proctree lock and the process lock are held when updating p_pptr and
  p_oppid.  When we are just reaading p_pptr we only need the proc lock and
  not a proctree lock as well.
