Daemon shutdown delayed by "broadcasting node event"

When I shut down the daemon with `^C`, there is a 5 second pause, and then I get an error message "timed out broadcasting node event".

```
DEBU[0056] start clean shutdown of cluster resources...
ERRO[0061] failed to send node leave: timed out broadcasting node event
```

This seems to be new on master in the last day or so. I think it's caused by #32283
