That is no longer true. It is now documented that slots will be called 
in the order they are connected.

As Bo sais: an API for that would be annoying at best, for something you 
need only rarely. Why not create more than one signal that you emit in 
order, or just make the object doing the processing emit a signal 
itself, and connect to that for your next step processing.
