That's what the WIP is pretty much doing (now), except that it
includes keystone (as lib/placement expects it). It's not super
slow, but nor is it super fast, and it seems wasteful for something
as tiny as this to not be super fast.

I have a followup in progress which is uses the "base" job, but it is
taking some time to get right.

P.S. Can we make the default reply-to for the new list be the list?
This is one of several areas where I disagree with jwz.
