| * Contact: Mike Marshall <hubcap@omnibond.com> |
| * Description: |
| * The perf_counters cache statistics have N, or |

| * Every perf_time_interval_secs the (first) |
| * samples are reset. |
| * |
| * If N is greater than one, the "current" set |
| * of samples is reset, and the samples from the |
| * other N-1 intervals remain available. |
