"so I can manage other server tasks distinctly" doesn't make a lot of
sense as a motivation here. Maybe that's because you don't have the
right idea about how to write servers with Twisted yet, or maybe it's
just because you haven't explained your requirements sufficiently.

It's possible to run the reactor in a different thread, but the reason
to do so is usually that you already have a second mainloop which you
can't easily integrate with the reactor's mainloop. In other cases, you
can typically accomplish whatever you need without starting any threads.
