return_statement: return threads
docstring: Starts all queue runners collected in the graph.
  
    This is a companion method to `add_queue_runner()`.  It just starts
    threads for all queue runners collected in the graph.  It returns
    the list of all threads.
  
    Args:
      sess: `Session` used to run the queue ops.  Defaults to the
        default session.
      coord: Optional `Coordinator` for coordinating the started threads.
      daemon: Whether the threads should be marked as `daemons`, meaning
        they don't block program exit.
      start: Set to `False` to only create the threads, not start them.
      collection: A `GraphKey` specifying the graph collection to
        get the queue runners from.  Defaults to `GraphKeys.QUEUE_RUNNERS`.
  
    Returns:
      A list of threads.
