Looking at the changes in question I wonder if it is the change to AffineTransform: http://trac.webkit.org/changeset/167017

AffineTransform is used a lot in Canvas. On each save() with a transform we create another AffineTransform on the stack. I could be absolutely wrong though and it is not this particular patch, or it doesn't even matter that much.
