Use XMonad.Util.SpawnOnce.spawnOnce. If you want to use SpawnOn as well
then you'd need to write your own spawner combining the two.

The more general way to do it is:

    as <- io getArgs
    when (null as) $ do
      {- your startup code here -}

which takes advantage of the fact that restarts pass --resume as a
parameter, followed by the serialized xmonad state.
