title: @Background and screen rotation when using AndroidAnnotations, how to make sure that the callbacks are received?
body: <p>When using the @Background annotation we start a new thread. And if we
  while this thread is executing where to rotate the screen, will we
  then lose the callback from that thread or how is that handled? With
  the Loaders this is sorted out behind the screen so we don't have to
  worry about the problems that occurred frequently back when we used
  async tasks.</p>
  
  <p>But how does the @Background annotation deal with this ?</p>
