      Currently the applier must (sequentially) do the following in a loop:

      1. batch oplog entries
      2. apply and record in local oplog
      3. journal, including minvalid
      4. report/update-position

      The task here is to break the last two steps (journal + reporting) into a separate process which doesn't block the next batch from starting/applying. This should allow higher throughput on the replicas without adversely affecting latency.
