[New-bugs-announce] [issue6381] test_urllib2_localnet sporadic failures closing socket

[R. David Murray]

New submission from R. David Murray <rdmurray at bitdance.com>:

Gentoo linux, r73699, I'm seeing sporadic failures in
test_urllib2_localnet in the following two tests:

test_sending_headers
test_proxy_with_no_password_raises_httperror

It happens about once every other run in one or the other of those.  I
don't see any problems on 2.6-maint or py3k.

In both cases it is failing in the close.  Here is an example traceback:

test_sending_headers (test.test_urllib2_localnet.TestUrlopen) ...
