Disk cache: More instrumentation for the cache.
Now we separate data between before and after the cache
is full. Also, reduce the rate at which a particular
client sends data to be only once a week. The effect is
that the histogram data will only have one value per client,
and the same client will not be "voting" on more than one
version (release) at the same time.
