That's your incorrect assumption; you can stop reactors. 
reactor.crash(). Usually one does this from some callback within their 
test. I've written tests with both iterate() and run()/crash(); the 
latter is usually more natural to me. I don't remember enough right now 
to try to make a blanket assertion about which one is better, though 
(maybe I should write more tests again ;).
