 // A SingleThreadTaskRunner is a SequencedTaskRunner with one more
 // guarantee; namely, that all tasks are run on a single dedicated
 // thread.  Most use cases require only a SequencedTaskRunner, unless
 // there is a specific need to run tasks on only a single thread.
 //
 // SingleThreadTaskRunner implementations might:
 //   - Post tasks to an existing thread's MessageLoop (see MessageLoopProxy).
 //   - Create their own worker thread and MessageLoop to post tasks to.
 //   - Add tasks to a FIFO and signal to a non-MessageLoop thread for them to
 //     be processed. This allows TaskRunner-oriented code run on threads
 //     running other kinds of message loop, e.g. Jingle threads.
