[Twisted-Python] scaling with lots of clients

Hi Itamar,

on re-reading I see nothing particular about process pooling being a bad idea. 

I see the explanation of spawning processes from the reactor here:

http://twistedmatrix.com/documents/current/core/howto/process.html

This seems to be designed for spawning processes for compute purposes which no doubt has a lot of use cases. I'd like ot spawn 
processes to handle user communication however. THe only thing that I can think of is multiple processes each with their
own reactor handling communication, and one or more other processes to handle compute. Thoughts?

THanks for your help.
