Casual inspection of Axon.ThreadedComponent identified a bug:threadedcomponent may never properly terminate if, when the thread (main() method) terminates, one of the inqueues in full and there are still messages waiting at the corresponding inbox.

This branch adds test suite coverage of this issues and fixes the bug.

Discussion

To my mind this could be deemed a bugfix. It is certainly not really a tangible API or feature-set change.

I've added to the docstrings to provide clarification around shutdown behaviour to people writing threaded components. Its basically documenting the situation as-is, rather than being a change in behaviour (aside from the bugfix aspect!)
