While generally true, you're missing Graham's point in this particular
case.  The idea that I think he's suggesting is that the GUI user will
have to explicitly request a job status.  On the server side, sending an
initial job setup or requesting job status is a lightweight operation.
If the GUI is not intended to be robust, I think it's not reasonable for
the GUI to hang while waiting for a response.
