DG is trying to watch your progress, and I have continually offered to help. I really don't care if you hack my code, but I think that you might be running into some historical mistakes. BTW, have you found/fixed the non-blocking swap pager problem yet. It seems that existing bugs should be fixed first. -- John | Never try to teach a pig to sing, dyson@iquest.net | it makes one look stupid jdyson@nc.com | and it irritates the pig.
