-/**
- * BatchedThrottle is a {@link SleepThrottle} that uses batching to achieve much higher throttling rates than a sleep
- * throttle can. Sleep throttle has difficulties once the rate gets above a few hundred hertz, because the JVM cannot
- * generate timed pauses that are that short. BatchedThrottle gets around this by only inserting pauses once every so
- * many calls to the {@link #throttle()} method, and using a sleep throttle run at a lower rate. The rate for the sleep
- * throttle is chosen so that it remains under 100hz. The final throttling rate of this throttle is equal to the batch
- * size times the rate of the underlying sleep throttle.
- *
- * <p/>The batching calculation involves taking the log to the base 100 of the desired rate and rounding this to
- * an integer. The batch size is always an exact power of 100 because of the rounding. The rate for an underlying
- * sleep throttle is then chosen appropriately.
- *
- * <p/>In practice, the accuracy of a BacthedThrottle skews off but can sometimes even be reasonable up to ten thousand
- * hertz compared with 100 Hz for a {@link SleepThrottle}.
