Is there actually a reason we can't have two forms of SCHED_FIFO. For hard RT the existing behaviour is a lot more useful and it is hard to see how you'd emulate it. > quite frankly, most programmers aren't "supposedly bad".

"real man" programmers stare at the code in Zen contemplation and debug by powercycling - thats one thing even hard RT processes can't beat.
