/CHEAT

   /CHEAT={ERRORS | EVENTS | NONE}

   Specifies the level of cheating allowed on the X protocol for
   the sake of improved performance. The X protocol guarantees to
   the requesting party that all corresponding replies, events, or
   errors are returned to the requester in the same order as the
   original requests. The ERRORS option allows the proxy server to
   violate the X protocol with respect to errors. The EVENTS option
   allows the proxy server to violate the X protocol with respect
   to errors and events. The NONE option specifies that no protocol
   cheating is allowed.

   The default is /CHEAT=NONE.

                                WARNING

      Some X applications may rely upon the correct ordering
      of events and errors. Enabling cheating may cause these
      applications to fail. Use this option at your own risk.
