A quick check demonstrates that exceptions do not get distinct status 
codes.  BTW: how could they?, you can create new exception types, there 
is not a bounded number of them.

On my Mac, Python 2.7 exited with a status code of 1 for 
ZeroDivisionError, NameError, SyntaxError, IndexError, and KeyError.
