The attached testcase is slower than necessary on trunk. It changes the contents of the text node in a block 100,000 times. It's 3x slower for white-space:normal than white-space:pre in my debug build. In the white-space:normal case we keep recreating the frame for the text because we've marked the text node with FRAMETREE_DEPENDS_ON_CHARS. We can fix this using the scheme in bug 495385 comment #57.
