If it's a small hunk of work, maybe one of the folks who wants the overcommit turned off can do the work and get it committed or post patches. It would allow the arguments to be decided by experiment. It seems we're well past the point of convincing anyone verbally. I'm not going to do it because (1) I like my overcommitted system just fine, thanks and (2) I don't know the VM system well enough to walk in and change it. - ---------------------------------------------------------------------- Ted Faber faber@isi.edu USC/ISI Computer Scientist http://www.isi.edu/~faber (310) 822-1511 x190 PGP Key: http://www.isi.edu/~faber/pubkey.asc -----BEGIN PGP SIGNATURE----- Version: 2.6.2 iQCVAwUBN4vXDYb4eisfQ5rpAQE8oAQAmVUZhXtDdils+lgxLCZsBKauA6VmPRTN pQjxc1IY5mslvzLq1yt9c+lT+4xplRs+bLWTK3k2IzvalZ6BzIB9pYT8bq2Rz+6h nBLQNkiQql1y0Ld8SrofJPIbbl2LQhLfT8T5PNz5PpqP4DD7z7p8JDJawnL0y1dq ws6YnHSJQ1A= =JcZA -----END PGP SIGNATURE----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
