```
spawnCapturing(executable: String, arguments: [String]) -> (
    output: String, error: String, status: Int32
)?
```

Runs `executable` and captures what it prints, without this library.

`posix_spawn` rather than `Process` or `popen`: this runs while the runner
plans tests on several threads, and a fork from a multithreaded process can
deadlock in the child before it execs, leaving its pipes open forever.

## Parameters

- `executable` (`String`)
- `arguments` (`[String]`)
