In the function MessagePort::close, the "m_closed = true" must be executed at the end of function, not at the beginning. Or, the m_entangledChannel->close() will not be executed. And it resulted in the failure of MS bench mark messagechannel_close.htm. You can try it from http://samples.msdn.microsoft.com/ietestcenter/WebWorkers/messagechannel_close.htm

You can use a series of methods for tests (e.g. debug("..."), shouldBe("...") etc). Please look at other layout tests using them.

I am following the format of LayoutTests/fast/events/message-port-clone.html, it seems that all of MessagePort related test cases used this format.
