 	// To enable, set to `true`. The sentinel-based rate limiter delivers a smoother performance curve as rate-limit calculations happen off-thread, but a stricter time-out based cool-down for clients. For example, when a throttling action is triggered, they are required to cool-down for the period of the rate limit.
