This code should work perfectly; there's nothing wrong with invoking
callLater while the reactor is running.

LoopingCall is the already-implemented version of this. I'm not really
sure if thinking in terms of recursion is a useful Twisted idiom,
though. On the one hand, Python doesn't handle lots of recursion very
well; on the other hand, this isn't really Python function recursion.
