[Gtk-sharp-list] Force UI Update?

I have a Gtk# application where the processing of a menu item may take 
many seconds. I want to change the cursor to a Watch before the actual 
processing takes place, and then change the cursor back to Arrow when 
done. For example:

     this.GdkWindow.Cursor = new Gdk.Cursor(Gdk.CursorType.Watch);
     this.GdkWindow.Cursor = new Gdk.Cursor(Gdk.CursorType.Arrow);

With this code the watch cursor is never displayed because UI updating 
normally only occurs during idle processing, which of course does not 
occur until after OnMenuItem returns.

Is there a way to force the update to display the watch cursor without 
DoLongProcessing using a separate thread?
