Use a signal for updating the dispatch status

The cost of connecting a signal may be a bit high, but it's comparable
to looking up the invokable method. However, QMetaMethod::invoke has a
higher cost than a signal-slot emission -- though in any case they're
both dwarfed by the cost of allocating the QMetaCallEvent and the
posting of it.

This is much more readable, though.
