http://trac.webkit.org/changeset/164409 caused a number of ASSERT to fire on iOS. true was used in the call to m_performCallbackWithReturnValue (instead of false) and false in invalidate (instead of true). This change also reintroduced the use of isMainThread on WebKit2 which doesn't work on iOS and should replaced with RunLoop::isMain().
