If I am out of order at all, please direct me to the right way to submit this issue / proposal for enhancement. This patch has been tested in production and works around the dependency on= a semaphore for popular programs like ruby, memcached, mysql, and redis, and = for using USDT probes without impacting performance when not attached. Thanks for taking the time to review this bug, I look forward to hearing yo= ur feedback and suggestions, -Dale --=20 You are receiving this mail because: You are the assignee for the bug.
