"After your shift, please try to follow up on the bugs you filed weekly. Kick off new bisects if the previous ones failed, and if the bisect picks a likely culprit follow up to ensure the CL author addresses the problem. If you are certain that a specific CL caused a performance regression, and the author does not have an immediate plan to address the problem, please revert the CL."
