exit() is inserted into the built-ins by site.py. This means it may not 
be available:

PS D:\> py -c "exit('bye ')"
bye
PS D:\> py -S -c "exit('bye ')"
Traceback (most recent call last):
   File "<string>", line 1, in <module>
NameError: name 'exit' is not defined

I have no idea if this is of any practical relevance...
