Also quick thing, in order to prevent too much cruft, could you
please move this patch before patch 2? You introduce the bool in
2 and then move it to the end in 3, better for you to reorder it
first and add the bool after, otherwise you get these "ping-pong"
style changes (Andy's words). My reviewed-by still stands either way,
so feel free to add it once reordered.
