// allow mocking_utils::inject_on_return to work. Thus the test has to patch_and_return().
// Unfortunately, this means that the resources are not actually cleaned up, and thus other tests
// may return incorrect results. By having it in a separate process we ensure that the resources
// will at least be cleaned up by the process dying.
