    Description

      Checkpoint Manager with P2P (MB-9982) can experience potential hang due to the handler not watching out for when checkpoint manager exits.

      The stack trace of interest would be:

      #       0x9c2d92        github.com/couchbase/goxdcr/pipeline_svc.respToGcCh+0x772                                       /home/couchbase/jenkins/workspace/couchbase-server-unix/goproj/src/github.com/couchbase/goxdcr/pipeline_svc/checkpoint_manager.go:2769
      		 
      #       0x9c2d0f        github.com/couchbase/goxdcr/pipeline_svc.(*CheckpointManager).stopTheWorldAndMergeCkpts+0x6ef   /home/couchbase/jenkins/workspace/couchbase-server-unix/goproj/src/github.com/couchbase/goxdcr/pipeline_svc/checkpoint_manager.go:2762
      		 
      #       0x9c9594        github.com/couchbase/goxdcr/pipeline_svc.(*CheckpointManager).periodicMergerImpl+0x194          /home/couchbase/jenkins/workspace/couchbase-server-unix/goproj/src/github.com/couchbase/goxdcr/pipeline_svc/checkpoint_manager.go:3487

      As a result, over time, there will be a large number of Checkpoint Manager zombies lying around and unable to be cleaned up, leading to memory leak.
