I posted too soon. Apparently the image setting had not taken hold, and when I did disable it the problem went away, both in Iceape and Konqueror. This seems odd because the page is mostly text, with only a few small images. Now I am guessing there is some kind of image library issue.

Just to clarify what you're seeing in top: 0.0%wa ?

I'm not sure I understand myself. I stopped it while scrolling and copied the first few lines below:

I've found that the browsers pre-render and store stuff in memory which
slows down the system when it starts to swap, or it saves stuff to the
disk cache with the same result.  Since I often access my browser via
ssh from my slow box, I've found that Konq stores rendered pages in the
Xorg server whereas iceweasel stores it locally.  My X terminal box only
has 64 MB ram so if I need to view a complex/graphical page or multiple
tabs I'll use iceweasel, otherwise I like Konq.

I don't know if those issues apply here. I have some large applications running (e.g. mythbackend) but I also seem to have plenty of memory, and top indicates there is no swap memory used.
