I feel silly replying to myself, but anyway...

I've been chatting about Deferreds on IRC with Drew, and he's made me
realise a few more things:
1) There's currently no way to cancel a Deferred
2) It looks like you can fire a Deferred multiple times.
You could workaround 1 by calling the errback if it wasn't for 2.
Point 2 surprised me; I expected Deferreds to be single shot (though I can
imagine that a multi-use Deferred would be ideal for some situations).
def _runCallbacks(self, result, isError):
Deferred._runCallbacks(self, result, isError)
But I think that this behaviour should probably be the default anyway (while
still providing the old behaviour).
