Mostly that GUEST_HANDLE isn't 32/64 invariant, and I didn't want to
have to introduce yet more compat shims.

If there's a strong consensus that GUEST_HANDLE is preferable then it
could be switched easily enough, but it seems kind of silly to
continue introducing more ABIs which aren't 64-bit clean.
