And who wrote the QA scripts you describe?  Complex systems have
complex failure modes.  Yes, there are clearly steps that can be
taken to minimize the problems, but anybody who claims that building
"robustness" into complex systems is anything other than "hard"
should spend some time reading the RISKS archives
(http://www.CSL.sri.com/risksinfo.html).
