You don't need to have multiple threads to communicate with multiple

This is because you're calling Twisted functions from non-reactor
threads. Twisted doesn't support this. The *only* threadsafe function
to call is reactor.callFromThread. You pass it a function to run in
the reactor thread.

If all you need is concurrent asynchronous I/O, you don't need
threads. Twisted is an *asynchronous* networking framework. You can do
all of your communication efficiently in one thread.
