This sucks due to the fact that we page in 4k blocks and most of the items that people are wringing their hands about are << 4K. It's even worse in that we often use a 4M page to back the kernel. It sounds like a neat idea, but basically it's just not worth the effort. There are better things to spend your time worrying about. 8) -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
