    Description

      In oplog cleaning, mongo use session->truncate to cleanup oldest oplogs.
      Which may still be held by snapshot-manager's uncommitted_snapshots.
      If session->truncate does not satisfy snapshot-isolation, snapshot-manager's uncommitted_snapshots are not dropped but the data are deleted.
      If session->truncate does satisfy snapshot-isolation, link SERVER-29150 should be a problem?
