Summary: Make urllib2.OpenerDirector instances pickle-able
Initial Comment:
urllib2.OpenerDirector would be pickleable if it were
not for the fact that a couple of urllib2 handlers
(which build_opener() adds by default) have function
instance attributes.
It's trivial to replace these instance attributes with
a method that delegates to the appropriate function,
thus allowing pickling.

The patch doesn't fix the problem; the opener remains unpicklable. If you
are still interested in this patch, please revise it accordingly; if not,
please close it. When you revise it, please include a test case, like this
one:
def test_1144636(self):
# Make sure OpenerDirector instances can be pickled
import pickle
try:
pickle.dumps(urllib2.build_opener())
except pickle.PicklingError:
self.fail("cannot pickle OpenerDirector instances")

Hmm, maybe this fault (can't pickle) will be fixed without
need for this patch in 2.5, due to the change to unbound
methods that was discussed on python-dev. I don't
understand that issue, so I can't say.
