------- Additional Comments from Roland Steiner <rolandsteiner at chromium.org>
Work-in-progress patch. Crashes during JS GC where Document::removedLastRef
seems to be called twice - the first time there must be some Nodes left
assigned to the Document that are not in the tree, that prevent destruction of
the document.
