extend ctrl process memory cache reads with freshness info - it is a bit too coarse grained at page granularity, that should've been easy to predict... in any case, to start addressing that, start keeping >1 hash key hash history in hash store layer, such that history may be preserved for a bit longer & diff'd with new key hashes
