Thanks! Although it turns out I'm at least partly to blame there - you
did give a reviewed-by on v5, but I didn't add it here since I'd made
significant changes - I should have checked and called that out, my bad.

I'll be working on that for 4.5, indeed. Getting the initialisation
order sorted out also stands in the way of converting 32-bit to the
common ops, so it's very high up my priority list.
