Reviewer: Joel Koshy (was: Guozhang Wang)
[~jjkoshy] Could you help taking a look at this one or could you give me a
heads-up on the context?

> Rate.measure() is called, it calculates elapsed time as now -
> stat.oldest(now).lastWindowMs. But the stat.oldest(now) may equal now due to
> the way SampledStat is implemented. As a result, Rate.measure() may return
> Infinite.
> This bug needs to be fixed in order for quota implementation to work properly.
