This revision makes a number of refinements and tweaks. The biggest change is a slight renumbering of the return codes which will break existing code using this patch series. I believe this patch is in good shape, and I don't see the need for any more API changes at this point. I plan to start using this revision more extensively, and I'd certainly appreciate any testing.
