Bug #648605 contains some nice work around implementing the LRU-SP algorithm for the disk-cache. The conclusion in that bug indicates that this will be too costly in terms of extra memory-consumption or alternatively in terms of CPU-usage.

We should set up an A/B test to evaluate memory and CPU usage, cache hit-rates, and (if feasible with current timer-granularity) time to find an entry and time to find the right entry to evict. The buckets of the histogram should represent number of entries in the disk-cache.
