Even if you compile your left hand into your right hand.  See Ken Thompson's
"Reflections On Trusting Trust" (http://www.acm.org/classics/sep95/).  To
complete the references, Reference 4 ("An unknown Air Force document") is
Karger & Schell's paper on a Multics pen-test, which is available at
http://www.acsac.org/2002/papers/classic-multics-orig.pdf

Karger and Schell did a "30 years later" retrospective, also available at
http://www.acsac.org/2002/papers/classic-multics.pdf

Between the India/Huawei thing and the MS05-039 mess, this is a good time for
everybody who hasn't read all 3 of them to read them - under 40 pages for all 3,
and the 24 pages of the first Karger&Schell you can probably skim.....)
