Still, I wouldn't recommend using the subprocess module in a Twisted application, and multiprocessing even less. 'subprocess' uses select(), which means that if you are running processes in a server handling a large number of connections with a reactor that you've selected for that job, you will occasionally notice that '.communicate()' will blow up because your file descriptors are too big to fit into a select() call.

I'm pretty sure Twisted's process.py uses select() in some cases... possibly on import though, which would be less of an issue, I forget.
