From 45ca9874955b1eaf3d941b7a278b594fad50d4ee Mon Sep 17 00:00:00 2001
From: Antoine Pitrou <solipsis@pitrou.net>
Date: Sat, 13 Nov 2010 00:28:53 +0000
Subject: Switch from gmane to another provider for NNTP tests (as gmane isn't
 reliable enough).  Also, use setUpClass in order to connect only once per
 test run.
