Well, or just use port 0 like we've done for decades, read what port got used, then use that. No more port collisions ever. I thought most people were already aware of that by now, but judging from that project even existing, seems I was wrong.
That’s a little different, right? Using port 0 would imply that clients have not hard coded what port they should connect to and also we don’t mind having duplicate processes occupying other ports which are no longer on active use
