I don't know enough to judge if that patch is correct or not, but the description "very unstable" is a bit exaggerated. This is not a condition that will see your machine blowing up and falling over every ten minutes, or even every 10 days. In fact you'll only run into it if you are running your machine particularly hard and doing memory intensive things. If it was as bad as that article makes out there would be an unending series of complaining e-mails to this list, the freebsd-stable list, the freebsd-hackers list and probably any five other freebsd mailing lists you care to mention. That just hasn't happened. Remember that the whole DragonFly BSD fork was the result not just of arguments about the technical direction of the FreeBSD project, but due in part to personality conflicts and politicking between various cliques of FreeBSD developers. It's quite possible that the patches' author still has issues with some members of the FreeBSD project. By all means try out the patch provided. If you prefer, try out DragonFly BSD -- but I wouldn't go betting the whole business on it just yet. DFBSD has yet to make it's 1.0 release. Keep your production systems on one of the FreeBSD 4.x-RELEASE branches for the time being, and wait and see what happens with FreeBSD 5-STABLE and DragonFly BSD 1.0 release.
