  // If we want to avoid this, we could create the InProcRendererThread
  // directly with _beginthreadex() rather than using the Thread class.
  // We used to set this flag in the Init function above. However there
  // other threads like WebThread which are created by this thread
  // which resets this flag. Please see Thread::StartWithOptions. Setting
  // this flag to true in Cleanup works around these problems.
