There's nothing special about a .tac file with respect to spawning processes, it's just another way to instantiate a Service object.  You just need to change the spawned process's arg list from "[executable, __file__, str(port.fileno())]" to something like "[executable, 'twistd', '-n', '-y', __file__, str(port.fileno())]".
