Running the test suite under Windows (I'm using '98 
SE) leads to a WindowsError being raised.

test_init.py specifically tries to catch a 
WindowsError with error code 3 (which occurs when the 
call to shutil.rmtree(self.dir) fails), but it doesn't 
catch it and the error is raised to the user.

The problem appears to be due to the fact that 
WindowsError subclasses OSError, but OSError is tested 
for first and its error code checked against some 
number that isn't 3; when the check fails the error is 
propagated, and the WindowsError clause is never 
reached.

I've fixed this on my own copy by changing the order 
of the except statements so that the more specific 
WindowsError clause comes first: if the exception 
really is a WindowsError, it will be dealt with 
specially; if it's just an OSError, things should 
proceed as before.

Cheers,
Steve
