Note

This method must be called in the main thread

Warning

This method requires that the lock is held!

A call to this method will either:

• run a message requested to run synchronously on the main thread if there is one (and return afterrwards),
• wait for the worker thread to notify it if the worker thread has pending work,
• or simply return if neither of the conditions above hold
