Why on earth would you use signals for that?

What's wrong with a simple list where you store interested parties and 
then invoke the method on the object containing the list, method that 
would walk the list and inform all the interested parties?

You are trading at most 50 lines of simple, debuggable code with 
hundreds of lines of unfathomable, layers of layers upon layers of 
templates of uber-complicated code that just manages to invoke a method 
on a bunch of objects?

Really, my questions from the past post are in part rhetorical - that 
is, I would like to use signals (hopefully some future, enhanced 
variation) for GUI event notifications (across threads as well).
