Summary: urllib cannot open data: urls

Initial Comment:
Python 2.4.2 cannot open data: urls using open_data().

Appears to be because of importing cStringIO and not
being able to reference fileno.

==============================================
Example fail output:

Traceback (most recent call last):
  File "test_open_data.py", line 6, in ?
    response = opener.open("data:,A%20brief%20note")
  File "/usr/lib/python2.4/urllib.py", line 185, in open
    return getattr(self, name)(url)
  File "/usr/lib/python2.4/urllib.py", line 559, in
open_data
    f.fileno = None     # needed for addinfourl
AttributeError: 'cStringIO.StringI' object has no
attribute 'fileno'

==============================================
Example code to generate failure:

import urllib

# data:,A%20brief%20note

opener = urllib.URLopener()
response = opener.open("data:,A%20brief%20note")

==============================================
Note: works in 2.2 version of library.

Problem appears to be here in 2.4:

        import mimetools
        try:
            from cStringIO import StringIO
        except ImportError:
            from StringIO import StringIO

whereas 2.2 reads:

        import StringIO, mimetools, time
