This software is bug-free. It is perfect, as perfect as human beings
have achieved. Consider these stats : the last three versions of the
program -- each 420,000 lines long-had just one error each. The last
11 versions of this software had a total of 17 errors.

But that just proves the point: despite all that careful engineering,
"one error each" and "a total of 17 errors" != "bug-free".
