          A closed rendezvous means all future attempts to re-rendezvous within
          same job will fail.
  
          ``is_closed()`` and :py:meth:`set_closed` have semantics of eventual
          propagation and should not be used for synchronization. The intention is
          that if at least one node decides the job is finished, it will close the
          rendezvous, and other nodes will soon observe this and stop running as
          well.
