0000    0 Structure      LGFBK          LOGOFF control block
      LGFTRMLK is used to serialize terminal clean-up
      processing (for LOGOFF, FORCE, DISCONNECT or LOGON HERE).
      Terminal clean-up processing is done without console
      function mode serialization. Any task performing terminal
      clean-up must hold LGFTRMLK exclusive. If a second task
      tries to get the lock it will be deferred until terminal
      clean-up is complete. For instance if one user issues
      FORCE DISCONNECT and another issues FORCE LOGOFF, when
      FORCE LOGOFF goes for the lock it will be deferred until
      FORCE DISCONNECT completes terminal clean-up.
      Notes      : If a thread of execution requires both CFM and the
            LGFTRMLK, it must obtain CFM first and the LGFTRMLK
            later.  The LGFTRMLK should be released before the
            thread relinquishes CFM.
