One more note, I would strongly recommend we tag the trunk when we
remove the old allocator. There's some minor codegen issues that I'd
like to be able to come back and work on further once we've got the
ports converted to IRA. Having a tag which allows me to checkout and do
comparisons of IRA vs the old allocator would make that process much easier.
