> SimpleRateLimiter.pause() uses an uncheck cast of longs to ints:
> Thread.sleep((int) (pauseNS/1000000), (int) (pauseNS % 1000000));
> Although we check that pauseNS is positive, however if it's large enough the cast to int produces a negative value, causing Thread.sleep to throw an exception.
> We should protect for it.
