I do read -current, and I'm definitely not going anywhere near SCHED_ULE. I just tested both libraries with today's kernel and libraries, and was able to get a hard lockup with both libthr and libkse. Mysql seems to run okay. Starting a threaded pike process seems to be the killer. Unfortunately, pike's a pretty large app so it's not easy to get a stripped-down testcase. -- Dan Nelson dnelson@allantgroup.com
