Certain cases may require that a client demand exclusive access to the
      server, causing the processing for all other clients to be suspended.
      Such exclusive access is referred to as grabbing the server. CLX
      provides functions to grab and release exclusive access to the server.
      These function should be used rarely and always with extreme caution,
      since they have the potential to disrupt the entire window system for
      all clients.

              connections other than the one on which this request arrived.

                The forms to execute while the server is grabbed.
             
              Grabs the display server only within the dynamic extent
              of the body.
              ungrab-server
              is automatically called upon exit from the body. This
              macro provides the most reliable way for CLX clients to grab the
              server.
