This one too:

> Index: WebCore/bindings/v8/DOMData.h
> +WTF::Mutex& DOMDataStore::allStoresMutex()
> +{
> +    DEFINE_STATIC_LOCAL(WTF::Mutex, staticDOMDataListMutex, ());

This looks like it has race conditions.  Please add a comment about why it
isn't or consider switching to using AtomicallyInitializedStatic (from
wtf/Threading.h).
