The main problem seems to be that WebCore::markDOMNodeWrapper is called more
than once for the same Node*, which probably makes this algorithm n^2 at least.

If you set breakpoints on JSC::Collector::markRoots and
WebCore::markDOMNodeWrapper, pick a Node* at random, and do a text search in
the scrollback, you'll see your node appear many times. My current count is 9.
