I'm currently using the startup_hook and exit_hook to start and stop the alpn responder. This works fine as long as e.g. the invalid_challenge hook is called. If this happens the exit_hook is not called anymore and therefore the responder process isn't stopped.

Based on the hook description This hook is called at the end of the cron command and can be used to do some final (cleanup or other) tasks. it would expect that it is called at the end of the script, independently from any other hook.
