> JcrResourceListener.onEvent(EventIterator) keeps references to all Event instances in the passed iterator. This has turned out as a memory bottleneck e.g. in the scenario where a large sub-tree is copied and NODE_ADDED events for all nodes in that sub-tree are generated. 
> Furthermore Oak will be able to handle arbitrarily large transactions (Session.save). In such cases the EventIterator might contains millions of events.
