Safari Webkit Crashes My System Daily and Often

I have taken in my computer to the Genius Bar to fix this, I have also called Apple support to get this fixed, I have also tried several methods that others have offered to others having this problem to employ and fix there problem, but nothing works.

My system will freeze up and then all of the sudden there are 5-6 Safari Webkit not responding notes in the Force Quite dialog box. This occurs every 8 hours or so. Every other case that I have followed has yet to have a solution for this. SHOULDN'T APPLE just simply fix this?????

Please help, my finger is on the trigger to toss Safari once and for all.
