  Modified files:
    sys/kern             kern_sig.c 
  Log:
  - Move the second stop() of process 'p' in issignal() to be after we send
    SIGCHLD to our parent process.  Otherwise, we could block while obtaining
    the process lock for our parent process and switch out while we were
    in SSTOP.  Even worse, when we try to resume from the mutex being blocked
    on our p_stat will be SRUN, not SSTOP.
  - Fix a comment above stop() to indicate that it requires that the proc lock
    be held, not a proctree lock.
