But what you did here was translate word-for-word your dot-locking mechanism into flock: you gained nothing, and it is awkward: you use the -n option that means ?do not wait for the lock? in a loop that says ?waiting for the lock?, it is absurd.

Yes, I agree that it's absurd to have code that periodically warns you it's waiting for something else to complete, particularly when the only reason I found this was that it was warning me that it was waiting.
Far, far better to have it silently hung and never update the firewall. I'll change it straight away.
