      To solve potential clipboard races, clipboard grabs have an associated
      serial counter. It is set to 0 on registration, and incremented by 1 for
      each grab. The peer with the highest serial is the clipboard grab owner.

      When a grab with a lower serial is received, it should be discarded.

      When a grab is attempted with the same serial number as the current grab,
      the one coming from the client should have higher priority, and the client
      should gain clipboard grab ownership.
