  // = DESCRIPTION
  //   The JAWS_Reaper uses the default Thread Manager (while each
  //   concurrency strategy uses their own).  The idea is that the
  //   reaper will spawn a thread to reap the threads of a concurrency
  //   strategy.  This allows the main thread to reap the threads of
  //   the reaper before exiting.
