They don't discuss either problem. I expect you'd have to do the same
sorts of things people do with ordinary registers and stacks -- bundle
them up, somehow, and put them on the heap. I don't see how they have
any advantage over ordinary registers in these instances; indeed,
they're probably a little more awkward (but only slightly).
