Life as an Artificial Lifeform

I have had a problem that bugged me since weeks. The finder on my MBP (dual 2.4GHz) was taking up about 100% processor speed - always. That not only reduced my battery life to about 30 minutes it also helped fry the graphic card (which I am still not sure if it is actually fried or just acting up occasionally).
You boot up and have nothing on and still your computer feels like it has a single 100Mhz processor in it. I was about to replace the finder with some other finder like tool today when I accidently stumbled upon the fix - on the mac rumors forum. (Somebody say those rumors sites are not good for nothing).
Anyway the fix is simple - the problem it seems is that something is calculating all along - the theory is its calculating the volume size of your main volume all the time. It only happens so (and then repeatably) when you have "Show Item Info" on your desktop turned on and showing your volumes on your desktop (don´t know if that can actually still be turned off - you used to be able to).
So the fix:

1.) click on your desktop
2.) go to "Show View Options" under your "View" menu or hit cmd+j
3.) unselect "Show Item Info"

voilá cpu usage drops from 100% down to 0.2%

Now dear Apple FTFF.
