Try this on for size:

% python
Python 2.3.3 (#1, Jan 20 2004, 22:38:52) 
[GCC 3.2.2 [FreeBSD] 20030205 (release)] on freebsd5
Type "help", "copyright", "credits" or "license" for more information.
>>> class C:
...     def __getattr__(self, x): 
...             raise SystemExit, 'Aieee!'
... 
>>> c = C()
>>> hasattr(c, 'caffeine')
False
>>> getattr(c, 'caffeine')
Aieee!
%

hasattr swallows all exceptions, including SystemExit as you can see.
