Hi Darren,
Sometimes "that's wrong" is good news: Python Processes spawned using 
the twisted API twisted don't suffer any more from GIL limitations than 
any other Python Process. That's only true for threads. You seem to 
think the multiprocessing module does something that wasn't possible in 
Python before, but that's not the case, the twisted version just has a 
different API, but does essentially the same thing.
