Back when I used Windows daily, it used to annoy me that every morning the machine had to warm up again, to revive the state I'd left it in the night before. In NetBSD I learned that unused memory is unused, so why not use it? I have a feeling that "fast app launching" is the reason, as though Windows users were excitedly punching the Start button with a stopwatch. But maybe there's more to it than that? --jkl
