A possible fix could be to let the webserver pick a random free port each time it starts and then let Tor know which port that is. Might need some tweaks to the state management, making sure the webserver gets started first or at least waiting for it to start won't introduce a deadlock with Tor needing this port.

That sounds good - it could help to simplify the state mangement, too, especially if we did the same when stopping.
