public final class SleepingWaitStrategy extends Object implements WaitStrategy
LockSupport.parkNanos(1)) for the minimum
number of nanos the OS and JVM will allow while the
EventProcessors are waiting on a barrier.
This strategy is a good compromise between performance and CPU resource. Latency spikes can occur after quiet periods.
