There's probably some other optimizations as well. I don't know whether that makes it more (less code) or less (slightly more complex) readable, though. It does seem we should try to be consistent with onNeedKey, though. WDYT? Or we can just remove this wait since we don't do anything in the handler. jrummell 2014/03/21 20:20:39 Removed.
