More and more are wanting and now finding the Linux kernel to be more
RT capable. I seem to remember way back you saying it was one thing 
you didn't really care much about one way or the other. Thats OK. But, 
you _are_ the man. Put an end to this. Are you going to allow the long
understood meaning of SCHED_FIFO to change in the Linux kernel 
just to protect a few _supposedly_ bad programmers???

Mark
