Review Comment:
Thanks for the suggestion, this is a better approach, it preserves the
original behavior of continuously logging shutdown-in-progress signals, while
significantly reducing log noise. I've updated the implementation to use an
```AtomicLong``` and now the shutdown warning will be logged at most once every
10 seconds.
