It was 35 pages (!) on random number generators. I implemented one for my own work. It was pretty clear he was one of those people who is smarter than the rest of us. Rob's (and maybe other's?) description of the VM system he did makes me really want to read that code. Rob talked about it the way I talk about the SunOS 4.x VM system, very clean and easy to understand. I'm still waiting to hear someone talk about an SMP VM system that way. That stuff gets complicated.
