        If the user cancels exit, self.exitConfirmed = False, otherwise
        self.close() is called. This time, no prompt will appear because the
        game has already been aborted.

        queryExit will return False if exitConfirmed or exitReady are not True.
        Otherwise, queryExit will set exitReady to False and asynchronously start
        shutdown. After the reactor stops running, exitReady is set to True,
        and self.close() is called. This time it should fall through everywhere,
        having queryClose() and queryExit() return True.

        and it will reset exitConfirmed to None.

        Or in other words: If queryClose or queryExit find something that they
        should do async like asking the user for confirmation or terminating
        the client/server connection, they start async operation and append
        a callback which will call self.close() when the async operation is
        done. This repeats until queryClose() and queryExit() find nothing
        more to do async. At that point queryExit says True
