Please see below for a preliminary series on -rcu. I say "preliminary" because most (if not all) of my patchlets should be merged with one or another of yours. I split them out to make it easier for you to review my changes. Also, I need to swap your first two commits, if I am not mistaken -- they are switched for ease of testing. Thoughts?
