Actually, although that page was an easy one to reproduce a flicker,  
I have seen a more widespread flicker on a few pages that don't seem  
to have any plug-in based content. Since It happens so rarely, I  
didn't provide an example before. However since one such page did it  
for me again today I'll elaborate:

I have a tabbed folder on my Safari bookmarks bar that contains the  
following URLs in this order:

http://www.macintouch.com/
http://www.versiontracker.com/macosx/index.shtml
http://www.macnn.com/
http://www.thinksecret.com/
http://www.macosrumors.com/
http://www.macoszone.com/

When I click on that folder, all the pages start to open with  
MacinTouch being in the front tab.

Once in a while (maybe the first time every day?) Macintouch will  
draw and totally white-out several times in quick succession until it  
finally ends up with the finished content.

I imagine that this is partly due to images/css or other media coming  
in at different times that forces a redraw, but  I don't remember it  
ever whiting out between redraws before 10.4.7.

(This tabbed folder has usually been the first thing I click on when  
launching Safari, so I am sure I would have noticed it in an earlier OS)

Doing it again just now, I see that although Macintouch redraws a  
couple of times while loading, there is no white-out between them.  
Emptying the cache didn't help in reproducing it either.
