That actually was resolved, sort-of. In the episode (I don't know the title) with the immortal photographer who's looking for death. He became immortal becouse just as death was about to get him, someone else saw death, and died instead. At the end of the episode Scully is shot, and abut to die. However, just as death is about to get her, the photographer sees death, and dies instead. Thus Scully, like he was, is now immortal.
