 Description   

Something I noticed while analyzing work done under the ReplicationCoordinator mutex is that we signal all tailable oplog waiters while advancing the committed snapshot, which seems unnecessary and costly to do while holding the mutex. The CappedInsertNotifier already has its own mutex.
