I think the main problem is that you don't need to run a main loop (so
you can get rid of both references to self.__loop).  You could either
call connect_to_signal() in __init__() or in the function that gets
called whenever a property gets set.  It looks like you might want to
do this in __init__() if you're going to go with the method you have
laid out above.
