Or how about the Navy ship that was rendered immobile for 3 days because 
the windows screen harware that ran the ship's controls cause a blue 
screen of death.  Laughable if it wasn't so pathetic.

Well, let's look at the facts a little.  The USS Yorktown was disabled for 2
hours, not 3 days.  This was because an operator entered a zero into a data
field, which the database software wasn't able to handle and wound up
crashing.

If an application performs an operation that attempts to divide by zero on
UNIX or Windows, the process crashes if it doesn't set up an exception
handler.

The fault was entirely within the boundaries of the user mode code, not the
platform.
