More changelog. More comments, please. We don't want to COW THP's because we'll waste memory? A COW that we could handle with 4k, we would have to handle with 2M, and that's inefficient and high-latency? Seems like a good idea to me. It would just be nice to ensure every reviewer doesn't have to think their way through it.
