Seems reasonable. I gather that there are already caches with the ability to partition themselves so that records from different subtrees compete for different pools of cache entries. I'm also sort of surprised that we don't seem to have all that much experimental data about cache behavior. The MIT papers that Tony cited are interesting, but they're also ten years old.
