           Summary: PerformanceTests/CSS/StyleSheetInsert.html has a

http://trac.webkit.org/browser/trunk/PerformanceTests/CSS/StyleSheetInsert.html's run function adds new nodes in each run but doesn't remove them. As a result, run gets slower on each call, resulting in values like:
22.0, 26.0, 27.0, 31.0, 33.0, 35.0, 37.0, 43.0, 44.0, 45.0

We need to remove the nodes added in each run so that values follow a normal distribution.
