In fact they should, its impossible to develop two sets of real-time
applications and shove them on the same box without co-ordination.

SCHED_FIFO is an utter trainwreck, you're talking to the guy who gave a

The only reason we have SCHED_FIFO is because of POSIX, and its one of
those things where they fucked up worse than usual (mostly because
people often don't realize how broken it is).
