    Description

      When using at least once mode (BarrierTracker), then an interleaved arrival of cancellation barriers at the BarrierTracker of two consecutive checkpoints can trigger a flood of CancelCheckpointMarkers.

      The following sequence is problematic:

      Cancel(1, 0),
      Cancel(2, 0),
      Cancel(1, 1),
      Cancel(2, 1),
      Cancel(1, 2),
      Cancel(2, 2)
      

      with Cancel(checkpointId, channelId)
