You may want to research this a bit further, because I'm not 100% sure, but I think the sticky bit _used_ to do this. It doesn't do it in modern versions of FreeBSD. In general, I don't think there's any way to do what you ask. Except, why not just buy enough memory that the machine never has to swap? With current prices at cents/meg, it seems a pretty reasonable thing to do. -- Bill Moran Potential Technology http://www.potentialtech.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
