Comment:

 Been walking over this code now, both patch-by-patch and the overall
 change. I think it looks good. I've added some minor things that might
 need some fixing. The API looks sensible and the code seems pretty easy to
 understand when diving into it.

 There's still a lot of `XXX`'s in the worker code, which should probably
 receive some love.
