Description
Multiple MNReplicationTasks are being created for a single identifier and target replica node. Only one should be created. Review the locking code across the ReplicationManager instances to be sure that, although they all eventually get the lock, only one should create the task.

ReplicationEventListener.entryAdded|Updated was queueing events and releasing the lock before the timeout on the other CNs (to do the same). I reduced the timouts to 10 ms, seeing that most queing took around 50 ms. This should keep only one CN queueing the event.
