    Description

      Add a hook or modify the dbhash hook to check that the oplog matches across replicaset members after calling ReplSetTest.awaitReplication()

      This can't be done with a simple dbhash comparison because the oplog is a capped collection and the number of documents may not match. We will need to traverse the oplog and ensure that they have a common history by comparing each entry manually.
