The only purpose of this guard is to check for the instance being disposed already . Everything else ,

as all involved classes ( means we ourselves , the UndoManagerHelper , the SfxUndoManager , and the Undo actions
we create ) are inherently thread - safe , thus need no external lock ( in particular no SolarMutex ! ) .
