  Log:
  Remove process information leak from inside a jail, when
  security.bsd.see_other_uids is set to 0, etc.
  One can check if invisible process is active, by doing:
  
          # ktrace -p <pid>
  
  If ktrace returns 'Operation not permitted' the process is alive and
  if returns 'No such process' there is no such process.
