Oh. Yes, tmpfs might just about explain it: 58320 /tmp So it looks like I have a swap-free box for a time. I guess I'd better be careful... :) > There was 88 kB out to swap in your original /proc/meminfo, which we > may suppose was before Mapped went negative; but above shows more since. Yes, I expect so. It must've gone negative really rather early: and note that it's some distance below 2^64 by now, so it's still falling. If I wait for a billion years or so it might wrap around. :) -- `Blish is clearly in love with language.
