i actually don't buy that it makes the math a whit easier.  if i'm
writing the code (as i just did, for instance), i've gotta know how
many register-sized objects i'm putting out there.  which means that
i've gotta do an extra multiplication to get bytes.

I don't understand why doing it in terms of bytes is better...
and that makes access from C a lot harder: i.e. you'd have to
coerce it into an array of right-sized objects.  seems
sort of silly...
