That's right. But in this case the function in question ('port') does
indeed set this option.
However, it still might be the case that some other service is already
listening at that port, perhaps even some not-yet-terminated instance of
your application.
You can find out the culprit with
$ lsof -i :8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
picolisp 20278 app 16u IPv6 2098603 0t0 TCP *:http-alt (LISTEN)
