[Twisted-Python] Twisted and the Posh Module

[Ken Kinder]

Has anyone tried playing with Twisted and the posh module? I need to do 
some CPU-intensive stuff inside the reactor, which unfortunately holds 
on to the GIL. I was thinking of just making a deferToPosh() type of 
method in the spirit of deferToThread(), but forking on each operation 
would be pretty expensive. Which brings up the question of having 
process pools.

Has anyone done anything like this? I don't really need any interaction 
between the worker processes and Twisted, so in theory I could spawn off 
some worker processes early and just communicate queues of tasks to 
complete, independent of Twisted and the reactor.
