Future.resultNow / exceptionNow

[Alex Otenko]

Ok, state...

Looking at State - it seems there are three cases when resultNow will
throw. That's probably ok, as there is only one to look out for. But
exceptionNow will throw in two cases, which makes the check a little
inconvenient.

I still think it would be nice to either not throw at all, or have a
isCompletedNormally/Exceptionally.
