      When using a mock replication coordinator, namely in unit tests, we always update the committed snapshot to this timestamp if it is higher. However, this is not necessarily correct as there may be an outstanding writes to the oplog before this one which have not yet committed. Thus, the committed snapshot may erroneously contain oplog holes until those outstanding writes commit.
