I don't think you are imagining things, as I tend to see similar things.
Every time I see it though, it is firefox/seamonkey related ... and
stopping and then restarting the browser has fixed the problem for me.
I also notice that this happens when I have too many tabs open (I
sometimes get as many as 30 tabs open).
I never really looked to see how much memory was in use or the load ...
as I just chalked it up to too many tabs and some kind of memory leak or
another. As I stated before, closing then reopening the browser does
usually fix it for me.
Since I normally use either firefox 2.0.x or Gran Paradiso
(firefox-3.0alpha) as my browser, I just assumed it was a problem with
that. (and my issues may be unrelated to yours and caused by my use of

My hardware is a dual processor Xeon 2.0 ghz, 3gb RAM machine that is my
main workstation. I will actually take a look at my memory and see if I
can see anything weird the next time it happens.
