Well, to some extent, I have to wonder why all these pages are being requested if they aren't being used... Still, all we "really" need to do is make sure that we flag the space as definitely for sure already taken up; it doesn't need to be backed to swap unless it's been dirtied, because untouched allocated memory is allowed to contain random garbage. You don't need to actually store all the pages right away - just make sure that you have a place to put them, say, some swap space or something. -s To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
