He noticed issues setting this bit in SRRCTL after the queue was up, so doing it from the sysctl handler isn't enough and may not actually work correctly. This commit doesn't remove the sysctl path or try to change its behaviour. I'll talk with others about how to finish fixing that before I tackle that.
