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