Gerhard Postpischl is of course quite right; trapdoors are necessary during the
development of much softwar; and they are useful for later troubleshooting
tooe.
What has interested me more about this thread has been its preoccupation with
SVCs, which are at best obsolescent. There is nothing anyone can do with an
SVC that I cannot do, much less obtrusively, with a PC-based scheme.
The focus of one poster's notionally savvy auditors on SVCs is yet another
example, if more be needed, of their preoccupation with safeguards against
yesterday's threats. (I am reminded of the DEW Line, which we Americans and
our Canadian Allies managed to get operational only a year or so after the last
of the Soviet Union's Badger bombers it was to protect us against had been
retired.)
