Probably not. kswapd, if it is doing low-priority swapping, activates
4 times a second, not once every few seconds. However, swapping in
general could be the cause, if there are background daemons waking up
for a quick look at the world every so often. Also bear in mind that
even reading a file will cause a write in a few seconds time, as the
last-access timestamp gets updated on disk.

Cheers,
Stephen.
