Jeff Olson d41af3e002 core: fix breakage in TaskBuilder.future_result
the actual "fix" in this change is the chunk that moves
`let x = self.consume()` to after the option dance that results in
the `notify_chan` in TaskBuilder.try()

the rest is cleanup/sense-making of what some of this code is doing (I'm
looking at you, future_result)
