Just letting you know that this is still in my queue, but every time I
look at it, I go "I need to spend more time on understanding this".

So this is one of those pull requests that will be done next week,
after I have gotten everything else off my plate, and I have time to
look more closely into it.

If it can be chopped up into smaller pieces ("this is just the
preliminary work part which is all obvious and clear") that might help
me, but I'll get around to it eventually regardless.
