I've added a futex stressor that rapidly does wait wait timeout and wake futex calls to stress-ng. My intention is not to add too much complexity to stress-ng as the core intention of stress-ng is to rapidly exercise the interface in a specific way, rather than be a thorough and wide per- system

We've moved to the intel-pstate driver by default for 14.10 which is an improved frequency scaling driver. On some hardware we've had evidence of this pushing the CPU a little harder and some machines were running hot, so we've also included thermald to stop thermal overruns. Also, thermald has
