Um, each screen window remembers it's scrollback properly? C-a [ - to enter 'scrollback' mode, and you can use arrows there.

What they seem to describe is altscreen behaviour which can be disabled with "altscreen off" in .screenrc .

Oh, that's right. I'm so used to the terminal emulator's scrollback buffer keys I forgot that you just have to escape to get to this behavior. I suppose there's no way to have this work the way I want until/unless the terminal mode natively supported multiple sessions/screens.
