-For each host/plugin/type combination the C<network plugin> caches the time of
-the last value being sent or received. Every I<Seconds> seconds the plugin
-searches and removes all entries that are older than I<Seconds> seconds, thus
-freeing the unused memory again. Since this process is somewhat expensive and
