Well, since the example was MX missiles, I guess it should invoke the Ada
exception handler... the exception handler should then fix things up, and
continue execution... or run the "abort" procedures...

It's certainly better than having the missile overwrite some state variable
and go off course into a city somewhere because there was no checking.
