It'd be tough. One way might be a wrapper program that SIGSTOP'd and SIGCONT'd the program with some pauses, but that would be incredibly nasty and probably not too pretty. A better way could would be to wrap the program with a library implementing sleep() and friends differently, so they pause for N times as long. But even that doesn't help when the programs don't slow themselves down. I guess the only general solution would be an API into the scheduler saying "Don't give this program more than N% of the CPU", but I'm pretty sure we don't have one. It'd be neat, though... /usr/bin/too-nice-for-its-own-good 8-} -- Matthew Fuller (MF4839) | [EMAIL PROTECTED] Systems/Network Administrator | http://www.over-yonder.net/~fullermd/ On the Internet, nobody can hear you scream. _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
