(🐞) dmypy says "daemon has died" when it starts

```
👉 dmypy start
Daemon has started
👉 dmypy kill
Daemon killed
👉 dmypy start
Daemon has died
👉 dmypy start
Daemon is still alive
```

I think this is intentional, but misleading in my opinion. When running `dmypy start` and seeing "Daemon has died", leads me to believe that the daemon has died while attempting to start, not that it has died previously.
