  15.  PROBLEM:
  16.  ------------------------                                                                                                           
  17.  During high traffic situations a request for service on another thread can
  18.  become orphaned prior to completion.  If this happens then the completed
  19.  request does not know which process is waiting for it.  The fix is to scan
  20.  all outstanding requests whenever an orphaned response arrives.  All completed
  21.  requests will have their associated process notified.  Because of the traffic
  22.  involved this fix must be applied in order for the Distributed feature to
  23.  correctly operate.
