    Make spawn_n() stub properly ignore errors in the child thread work

    When we call spawn_n() normally, we fork off a thread that can run or
    die on its own, without affecting the parent. In unit tests, we stub
    this out to be a synchronous call, but we allow any exceptions that
    occur in that work to bubble up to the caller. This is not normal
    behavior and thus we should discard any such exceptions in order to
    mimic actual behavior of a child thread.
