Detail:
  Currently, there is no way of ascertaining the client handle that used to
    belong to a deleted object.  Thus applications cannot rely on this event
    to close down any associated data structures referenced via the client
    handle.  This event now provides the client handle and the class ID of
    the deleted object (application can check flags bit 0 to determine if
    they are valid).
