> From the parent issue, Todd reminds us of the old Jim Gray '5 minute rule' on
> whether to cache.
> In master, we were reporting age only it was the inactionable inverse of 'how
> long blocks are staying in the cache'.
> Let me add to our cache stats a histogram of age on eviction and change the
> UI reporting so it is age at eviction (plus stddev). The JSON version has
> percentiles (and if wanted, the old age report of age of items in cache).
