+Subject: [PATCH 2/3] Build circuits more readily when DisableNetwork goes to 0
+
+When Tor starts with DisabledNetwork set, it would correctly
+conclude that it shouldn't try making circuits, but it would
+mistakenly cache this conclusion and continue believing it even
+when DisableNetwork is set to 0. Fixes the bug introduced by the
+fix for bug 11200; bugfix on 0.2.5.4-alpha.
