As Russell points out, many people don't know what the difference
between "fail safe" and "redundant" is.

Perhaps as engineers we really should.  I've heard engineers misuse
the terms before.  It's an important distinction.
http://en.wikipedia.org/wiki/Failsafe is a poor explanation of the
concept.  Wikipedia DOESN'T know everything.

Anyone want to take a crack at it?  I don't feel like I have the level
of expertise required to do so.
