In many Unices, crucial kernel threads run at realtime priority with a static priority higher than is accessible to user code. That being said, however, you've got to be a privileged user to set real time very high priority on a thread, and if you do, you'd better know what you're doing. Any SCHED_FIFO thread should run for a time, then sleep for a time, or it *will* DOS everything else on the processor. -- Dr Peter Chubb http://www.gelato.unsw.edu.au peterc AT gelato.unsw.edu.au The technical we do immediately, the political takes *forever* - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
