I'm happy to post my current work, if it's considered helpful. The sole
intent of that work is to help the community understand the benefits of
the proposals I have made, so perhaps this patch does serve that
purpose.

The attached patch compiles, but I wouldn't bother trying to run it yet.
I'm still wading through the latch rewrite. It probably doesn't apply
cleanly to head anymore either, hence discussion.

I wouldn't normally waste people's time by posting a non-working patch,
the majority of the code is in about the right place of execution. There
aren't any unclear aspects in the design, so its worth looking at.
