Wait, so you're not really changing the cache while it's used, but you only create it once and then use it like a regular backing file? If so, the only thing we need to talk about is the creation, because there's no difference for using it. Creation can use the existing copy-on-read functionality, and the only thing you need additionally is a way to turn copy-on-read off at the right point. Or do I misunderstand what you're doing?
