In my experience, 'top' sometimes goes off into lulu land and claims
silly crap. For some reason - I recall that someone explained it to me
once, but I've lost the index to the brain cells containing the
explanation - it has a problem with some processes (e.g. XFree86) which
do some strange thing that 'top' can't cope with - so it just lies.
In other words, put not your complete trust in the reports of 'top';
'tis a weak reed.
A prudent navigator will never limit himself to a single method,
particularly one requiring ... a device that is subject to mechanical
damage or loss.

It would be interesting to go through all the possible combinations of
the three processes (if possible) to get a better handle on what
triggers it, though.
Does the machine actually bog when you see this report, or is it just
showing this stuff without any external effect?
