I think Emacs works the same with frame/buffers. What I really like in Emacs is not having "tabs" or anything like that. I can always open any file on the filesystem, why do I care what it is open currently? Only at the moment I want to switch do I want to see a list, but I don't want to select it like some neanderthal, I want to narrow it down by typing. I wonder how well this would work for a WM, though. Processes are a lot heavier than buffers so it kind of does matter how many are running. Unless it's a system like Android where any app expects to be oom killed at any time.
