Goto a long page with text/images and scroll up/down using the arrow keys.  The
CPU pegs out and the scrolling becomes v e r y   s l o w.
Example URL ?

No, that only got me up to 25% CPU.  (Is that high for a page like this?  I
don't know.)  I was browsing through
http://java.sun.com/j2ee/tutorial/1_3-fcs/doc/Overview2.html when I experienced
this.  It was most notable when the images were in view.  The higher CPU usage
seemed to correspond to bringing new content into view.  If I reverse and scroll
through previously seen content it seemed much faster.
