示例2: guessIdleTimeout

If we connect to the machine, send one initial query and then stop, how long
can we idle until the machine terminates our connection?
Testing shows that this doesn't seem to be one consistent timeout, and that
instead it's however long it takes until the wifi flakes out a little bit.
