The disco key subscriber could deadlock in a scenario where a self node update came through the control path into the mapSession after the disco key subscriber had taken the lock, but before it had pushed the netmap change, as both the subscriber and onSelfNodeChanged needs the controlclient lock. The subscriber can safely take the mapsession as the changequeue has its own lock for inserting records, and also checks if the queue has been closed before inserting.
