I'm replying onlist, because what I'm seeing is odd enough that others
may want to try this as well...

In Firefox 4.0.1 on my MacBook Pro 2.66mhz 4 gig of RAM, OSX 10.6.7,
highlighting that line bumped its cpu to 100%+. Also, though, clicking
and selecting several other lines did the same, or nearly as
high--near 100%. I got curious, and tried a couple other web pages. It
seemd rather random, but I could repeat this with other entire-line
selections, but not everywhere.

Next, I got _really_ curious, and tried it in Safari, and surprisingly
enough, while the CPU didn't jump to 100%, it did go up
significantly--from well under 10% to over 25%. Oddly, again, trying
other pages would increase CPU time, but nowhere near as much as with
your test page. I can't imagine what's going on, because it doesn't
look like your page has any CSS or JavaScript or anything
unusual--very basic html!

I can only guess that there is something about the text itself that
prompts something in the contextual menus of these apps to go haywire.
