Is it safe nowadays to run a process at idle priority? Or is there still the danger of priority inversion / a deadlock?
On FreeBSD 4.x you can run a process, such as setiathome, at nice level 19 and it will (almost) only ever get CPU time when no process of normal priority competes with it. FreeBSD 5.x is much "fairer" in this respect, which has the unpleasant result that such a background process will noticeably compete for CPU now. -- Christian "naddy" Weisgerber [EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "[EMAIL PROTECTED]"
