I had a look at: https://code.google.com/p/memcached/wiki/NewUserInternals#How_the_LRU_Decides_What_to_Evict which sais memcache will "evict" one that isn't expired if it cannot find an expired item. Am I correct to assume that it's evicting by LRU logic? Is this an ordered stack eviction, or are there any random bits in there?
