Description:
            The perf_counters cache statistics have N, or
            perf_history_size, samples. The default is
            one.

            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.

            Slots are requested and waited for,
            the wait times out after slot_timeout_secs.
