Of course, we don't need to change them all.  Try this:

That would be good candidate for a clean up but I'm not sure this should be
part of this already too long series.

If you don't mind, unless a global agreement is stated on that, I'd prefer
to postpone such a change once the initial series is accepted.

Actually, I think this can go in first, independently of the speculative
fault series.  It's a win in memory savings, and probably shaves a
cycle or two off the fault handler due to less argument marshalling in
the call-stack.
