    test-display-base: Avoid spurious errors due to listen failures
    To set up a listening socket usually you call in sequence:
    - socket;
    - bind;
    - listen.
    If you try to bind() to a port when another socket is already
    listening on that port, the bind() will fail.
    However, it is possible that the bind() may succeed and the listen()
    will fail, as demonstrated in the following sequence:
    - socket() create socket 1;
    - bind() to port N on socket 1;
    - socket() create socket 2;
    - bind() to port N on socket 2;
    - listen() on socket 1;
    - listen() on socket 2 <-- failure.
    When running tests (especially multiple tests running in parallel), it
    may sometimes happen that there are other tests already listening on
    the port that we are trying to use. In this case, we want to ignore
    this error and simply try to listen on a different port. We already
    attempted to handle this scenario, but we were only ignoring bind()
    errors and not listen() errors. So in the scenario mentioned above,
    the listen() error was causing the entire test to fail instead of
    allowing us to try to listen on another port.
