AFAICT the "processing" module does things like "fork"ing a running
python interpreter and then not immediately exec()ing.
I'm pretty sure that'll cause Twisted (and maybe lots of other apps) to
explode. However I note you're on Windows (which lacks fork()) so I'm
not sure what it does there.
Also, the Processing module communicates over pipes/fifos which will
conflict with Twisted and block the reactor (or the reactor will block
In short - nice though it looks, I don't think you can use Processing
with Twisted, or will ever be able to. It's a shame more attention
wasn't paid to this during development.
You could look at:
Having either of these implementations inside Twisted would be excellent
