Just noting that the JS version does not have this same exception now.

The JS version doesn't have a timeout so I guess that's fine?

/fixes #9901
It seems that #9827 introduced a bug where finalizers might not run in applications that are exited externally. I'll create a release straight after this PR is merged because this can be a relatively severe bug. This should revert the behaviour to what was in 2.1.17 but without the bug that was fixed (#9807)
One other thing is that this PR adds the
gracefulShutdownTimeoutmethod onZIOApp. This way users can configure how much time the runtime will wait before exiting after an external interruption signal is received. This is partially to mitigate issues where the app might hang on termination (e.g., #5185) or because of uninterruptible finalizers that never complete. I set the default value toDuration.Infinityin order to avoid breaking applications and to match the behaviour pre-2.1.17.I'll followup with:
