which looks correct compared to /proc/meminfo.
OTOH, ps(1) (and qps for that matter) show much higher aggregate swap
usage. A couple of intersting lines from ps avxww --forest:

plus another 8 or so xterms all with similar DRS vs RSS numbers. Qps
shows results similar to ps.
ps avxww|awk '{print $6 + $7 - $8}'|awk '{i += $1} END {print i}'
returned 470418 just now, when meminfo is claiming:
SwapTotal: 538136 kB
SwapFree: 515120 kB
Is this just a bug in /proc/meminfo?
