Hi,

I wanted to have a class hierarchy where .stop methods would make sure everything is cleaned up properly before reactors get stopped and such.

That's what services (twisted.application.service) are for. The stopService method of a service can return a Deferred. Since they're a tree, all you need to do is hook up the root service to the reactor (which is what twistd does for you) and all child services will get shutdown as well.
