It is certainly possible to detect some naif SVC-based schemes that return control to their invoker in key 0; it is not possible to do so in general; and it would not be enough to do only that.
Moreover, SVC-based schemes to this end are at best obsolescent; PC-based ones will be the villains of the future. Shane has warned me that by mentioning this I am encouraging auditors to erect barriers to the virtuous use of PC-based schemes too, and he is of course quite right. I am nevertheless reminded the USAF DEWLine Project, circa 1952-1992, which did perhaps come to provide adequate protection against over-the-pole incursions of the USSR's atomic-bomb carrying Badger bombers, but only well after those bombers had been retired from service.
