    Description

      The StateChangeNotifier takes a read lock and notifies listeners using a direct method call. This notification could lead to the listener being complete. At this point, it may decide to unregister from further status updates and this should be allowed. However unregister tries to take a write lock on the StateChangeNotifier and the result is a deadlock.
