Thanks Tim for working on this issue, I'm sorry I haven't been able to
leave code review yet -- I've been busy with a bunch of other things
and, since it's a large patch, I wanted to give thoughtful feedback.

Feel free to push some more commits to that PR. I can prioritize
getting you some feedback in the next couple of working days, just let
me know when you're ready for me to review.
