John Baldwin 1333047621 - 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.
