Because our swapper doesn't work that way. Generally speaking, swappers don't work that way anymore. Systems that suspend to disk are a corner case for FreeBSD. > Processes do still wind up in "sleep" state, completely paged > out, don't they? Observationaly, no. Unless I actually manage to run my system low on RAM, none of my swap is used even with ~5MB Eterm processes sitting unused for days. I suppose if I let memory get tight, they might get ditched in favor of disk cache, but I haven't seen that happen. Someone with a better grasp of the VM could give a more preciese answer. -- Brooks -- Any statement of the form "X is the one, true Y" is FALSE.
