Keep in mind that nothing in Twisted is thread safe, so you will have 
to write a state machine to process the results of your threaded 
calculations anyway.  State machines are really the point of Twisted.  
The framework itself is a huge repository of different techniques and 
examples for making writing state machines easy.

If you're going to write a bunch of blocking I/O in threads, you might 
as well write your own framework.  You literally won't be able to 
safely call any Twisted code that way.  As an aside, running lots of 
threaded clients will tend to scale much more poorly than multiplexing 
them all.
