>
> EstimatedHistogram treats adding value n as adding a value infinitesimally
> greater than n. This barely made sense for the original goal of latency
> tracking but is clearly broken for inherently integral data like
> sstables-per-read.
> Also, median() is broken, but even a non-broken median() would not be correct
> to use in mean row size reporting which is its only caller.
