The comments says it's not needed by in the case of:
---------------
from urllib2 import URLError

u = URLError(1)
u[-1]
Traceback (most recent call last):
  File "u.py", line 6, in ?
    u[-1]
AttributeError: URLError instance has no attribute 'args'
--------------
it's not what we excpect.
Attaching a patch to call IOError.__init__

I've changed URLError to call IOError.__init__().  That's an
improvement, but it's still not great.  The typical
EnvironmentError has a two- or three-tuple where item 0 is
the errno, item 1 is a string explaining the error, and item
3 is a filenumber.  The change will creates args, but won't
set errno or strerrror.  Code expecting an errno in args[0]
will be surprised.

What do you think?

This should be closed:

If anybody has any further bright ideas on making urllib2's
exceptions more beautiful, they can always submit a new patch.

Closing, per jjlee's suggestion.
