Thanks for looking at this!  I was hoping you'd review it, because
I thought there was a pretty significant chance that I'd missed some
fundamental reason it couldn't work.  I feel better now about it
being worth pursuing.

I consider the patch draft quality at this point: I didn't spend
much effort on docs or comments, and none on test cases.  I'll
work on those issues and come back with a v2.
