Comment 2 for bug 1485815

@bill yeah that's about right

I don't expect the daemon to keep track of totals and calculate the anything tho - he won't have a wide enough view to answer the question sufficiently for the cluster. But if he did a statsd/debug-log-line message in reconstruct_fa I'm sure I could figure out some way to aggregate across the cluster.

Measure is the first step towards optimize.
