* new settings for governors, +30% memory bandwidth
* CPU waste is better
* warm up frame_drop
* optional CORE arg for rtshield
* back off priorities of processes not critical to driving
* if it doesn't drive, it's not realtime
* err, resource. this should have been included
* reverse order to not spike
