OK. bear in mind that it's still a bit scrappy, but I'm releasing it early
to give you that time.

BTW, I wrote an earlier version of this patch which allocated the registers
automagically rather than the requiring the programmer to name them, but it
turned into such a mess that I gave up. IMO it's better to do this more
gradually, with this first patch making essentially no changes.
