// This API is not thread-safe:
//   - Start()/Stop() should only be called from the main (creation) thread.
//   - PostTask()/message_loop()/task_runner() are also safe to call from the
//     underlying thread itself (to post tasks from other threads: get the
//     task_runner() from the main thread first, it is then safe to pass _it_
//     around).
