Overall, I like this series a lot. However, I don't really see this as a
v3.7 material because we already have largeish pending updates to the
slab allocators. I also haven't seen any performance numbers for this
which is a problem.

So what I'd really like to see is this series being merged early in the
v3.8 development cycle to maximize the number of people eyeballing the
code and looking at performance impact.

Does this sound reasonable to you Glauber?
