My view would be that with 90 files touched this is a very large
patch, so that alone makes me wonder whether we should commit this
patch, so I agree with Noah and compliment him on an excellent
detailed review.

However, review of such a large patch should not be simply pass or
fail. We should be looking back at the original problem and ask
ourselves whether some subset of the patch could solve a useful subset
of the problem. For me, that seems quite likely and this is very
definitely an important patch.

Even if we can't solve some part of the problem we can at least commit
some useful parts of infrastructure to allow later work to happen more
smoothly and quickly.

So please let's not focus on the 100%, lets focus on 80/20.
