[Twisted-Python] Reactor.run() to be a non blocking call and run in background

Hi guys, I'm using twisted to host an ssh server.. My requirement that the python code I did needs to start the reactor and come out of the execution and needs to stop the reactor once stop is called.. But since the reactor. Run() seems to be a blocking one.. It isn't moving forward after starting the reactor.. Any work around on this would be appreciated.. Regards, Nandha Kumar S
