[Twisted-Python] reactor.stop

[Tsai Li Ming]

Dear all,

I understand we are not supposed to call reactor.stop() within twistd as 
the reactor is already running, therefore it will shut down the entire 
application.

Why does calling reactor.stop within my module will cause the 
application to shutdown? Is it because even when I import the reactor in 
my own module, it is still somewhat linked to the twistd reactor through 
the system event trigger?

Regards,
