Wow, these are a LOT of reads and a very small cache.
I guess the old page_launder() might be misbehaving in
this case, I've just finished the patch for a new one
(which seems to work nicely in the limited tests I've
thrown at it).

Here things get "interesting" ...
total memory: 127 MB
The memory taken by all your processes: 55 MB
buffer + cache: 10 MB
-----------------------------------------------------
missing: 62 MB
It would be interesting to get a listing of /proc/slabinfo,
in particular those lines which have a large number in the
4th or 5th column...

Rik
