If you emit a signal and the receiver lives on the current thread and 
the connect() call did not use Qt::QueuedConnection, then it is 
"blocking". If you use Qt::DirectConnection or 
Qt::BlockingQueuedConnection then it is always "blocking".

But if the receiver lives on another thread or if you specified 
Qt::QueuedConnection then the signal puts an object on the event loop 
and returns immediately.
