Perhaps I'm misunderstanding what you're trying to achieve, but...

Python is not multi-threaded:  Never has been, and from what I can tell, never 
will be.  Qt isn't going to be able to magically change that.  A QThread is 
going to be blocked by the GIL if your execution path strays back into 
/any/interpreted code.
