  Log:
  Rework stopping of procs.
  
  Before, proc_stop() would sleep until all running lwps stopped.  This
  break when a stop signal is actually coming from the console and is
  executed in the context of the idle thread.
  
  Now we count all sleeping threads as stopped and also set LWP_WSTOP to
  indicate so.  These threads will stop before return to userland.
  Running threads (including the current one) will eventually stop when
  returning to userland and will increase p_nstopped.  The last thread
  stopping will then send a signal to the parent process.
