Absolutely. A signaling mechanism, synchronous, is not hard.

If you want asynchronous, or if you want the signal executed in the context 
of a thread in case of multiple threads, that is another matter.

Although I am having difficulty seeing how you would decide which signal 
must be executed in what thread... an object does not automatically 
belong to a thread...
