>
> The TopologyEventHandler.handleTopologyEvent() javadoc should be updated with:
> * the fact that it should terminate quickly and not do any length operations
> (as this could potentially hold back any other handler and it was not
> intended to support long-running handle calls)
> * the fact that the handleTopologyEvent() caller could potentially hold
> locks and handleTopologyEvent() itself should be (dead-)lock free
