Howdy. We ran into this, or something very similar to this, today. We're
using `ConsoleAppender`.
Our disk was 100% full at the time, which I think is related? Here's parts
from my thread dump:
```

```
The main part that makes me think this is related to this issue is that once
again it's `OutputStreamManager:352` that's holding the lock forever.
