 Last week, metrics-web on yatei ran out of memory quite often.  The reason
 is probably that we're reading too much stuff from stats/ (in order to
 avoid parsing stuff twice) without garbage collecting aggressively enough.
 In particular, stats/archives-import-history and stats/bridge-stats-raw
 might be problematic.

 The workaround was to change max memory from 4G to 8G.  This fixes the
 problem for now, but obviously we can do better.
