Your understanding seems correct to me. :)  This is basically how the 
feature would be implemented.  Since David is using `twistd` though, he 
doesn't get to put extra code after the `reactor.run()` call.

http://twistedmatrix.com/trac/ticket/2182 is a ticket for adding a 
feature to `twistd` to make this easier.
