// Usage

let argv = CStringArray(["ls", "/"])
posix_spawnp(nil, argv.pointers[0], nil, nil, argv.pointers, nil)

// Is this really the best way to extend the lifetime of C-style strings? The lifetime
// of those passed to the String.withCString closure are only guaranteed valid during
// that call. Tried cheating this by returning the same C string from the closure but it
// gets dealloc'd almost immediately after the closure returns. This isn't terrible when
// dealing with a small number of constant C strings since you can nest closures. But
