I think it is there because we need to raise another (visible) frame  
when a frame is deleted.  This is standard behavior (and sensible).   
However, this should not occur if the other frame is hidden, i.e. if  
there is no visible and uniconified frame.  Im currently experimenting  
with something like this:

#ifdef NS_IMPL_COCOA
  /* term gets no other notification of this */
  if (for_deletion && FRAME_VISIBLE_P (XFRAME (selected_frame))
      && FRAME_LIVE_P (XFRAME (selected_frame))
      && ! FRAME_ICONIFIED_P (XFRAME (selected_frame)))
    Fraise_frame(Qnil);
#endif
