In the migration of the Ruby buildpack to use this crate I noticed a regression:
```

```
I isolated it to the `fun_run` PR heroku/buildpacks-ruby#232 and after some debugging found it was due to accidentally copying `child.stdout` for `child_stderr`. I added a test that verifies that stderr is redirected correctly.
