  37 /* This is a small class which can be used by all ports
  38    to temporarily suspend the busy cursor. Useful in modal
  39    dialogs.
  40
  41    Actually that is not (any longer) quite true..  currently it is
  42    only used in wxGTK Dialog::ShowModal() and now uses static
  43    wxBusyCursor methods that are only implemented for wxGTK so far.
  44    The BusyCursor handling code should probably be implemented in
  45    common code somewhere instead of the separate implementations we
  46    currently have.  Also the name BusyCursorSuspender is a little
  47    misleading since it doesn't actually suspend the BusyCursor, just
  48    masks one that is already showing.
  49    If another call to wxBeginBusyCursor is made while this is active
  50    the Busy Cursor will again be shown.  But at least now it doesn't
  51    interfere with the state of wxIsBusy() -- RL
