   // dispatch the task from a nested invocation of MessageLoop::Run.  Instead,
   // such tasks get deferred until the top-most MessageLoop::Run is executing.

   // The MessageLoop takes ownership of the Task, and deletes it after it has
   // been Run().

   // NOTE: These methods may be called on any thread.  The Task will be invoked
   // on the thread that executes MessageLoop::Run().
