        public static long rateLimitWrites()
        Rate limit writes in case indexes are lagging behind too far. The method returns immediately if all async indexes are up-to-date (updated in the last 30 seconds). If indexing lanes are lagging behind, however, the method will wait (using Thread.sleep) for at most 1 minute. If the method is called more than once per minute, it will sleep for at most the time that passed until the last call; that is, an application that is calling it a lot will be paused for up to 50%. This assumes indexes will be able to catch up in this situation.
        Returns:
        the number of milliseconds the call was sleeping
