if a node fails to report stats, the natural thing to do in re munin is to supress the data for that data series. the previous tahoe-stats would output whatever data was present in the stats_gatherer's stats.pickle, regardless of how old. this change means that if the gatherer hasn't received data within the last 5 min, then no data is reported to munin for that node.
