  71 /* This is a small class which can be used by all ports
  72    to temporarily suspend the busy cursor. Useful in modal
  73    dialogs.
  74
  75    Actually that is not (any longer) quite true..  currently it is
  76    only used in wxGTK Dialog::ShowModal() and now uses static
  77    wxBusyCursor methods that are only implemented for wxGTK so far.
  78    The BusyCursor handling code should probably be implemented in
  79    common code somewhere instead of the separate implementations we
  80    currently have.  Also the name BusyCursorSuspender is a little
  81    misleading since it doesn't actually suspend the BusyCursor, just
  82    masks one that is already showing.
  83    If another call to wxBeginBusyCursor is made while this is active
  84    the Busy Cursor will again be shown.  But at least now it doesn't
  85    interfere with the state of wxIsBusy() -- RL
