Overall, the multithreaded aspects of RemoteInspectorXPCConnection are too complicated. This should be simplified in someway. For now, address a couple possible issues:

    - multithreaded access to m_client (close(), and XPC event handler)
    - deref too early in close(), if close() is called, we will receive another XPC event (XPC_ERROR)
      - so deref after we receive the XPC_ERROR event
