Please take this as just a preview of early WIP. I think I may end
up doing moderate amount of refactoring as a preparatory step before
these patches, so nitpick-reviews are likely to become waste of
reviewer's time at this point.
I've pushed out a mostly-done reroll on 'pu'; I'll send them out as
patches for review tomorrow. I think I am making a good progress.
