I've scheduled time later this morning (pacific time) to take a look at this.

[jbweston]

Overall I agree with the approach, but I believe that we can make everything cleaner by only dealing with point IDs inside the runner itself. We only need to extract actual points at the interface between the runner and the outside world (when calling self.learner.ask and self._submit)
