   Automatic sanity-testing: PASSED, see http://jenkins.bluematt.me/pull-tester/ea89d521d604b6fa81cfe881313d8845a5f4f30c for binaries and test log. This test script verifies pulls every time they are updated. It, however, dies sometimes and fails to test properly. If you are waiting on a test, please check timestamps to verify that the test.log is moving at http://jenkins.bluematt.me/pull-tester/current/ Contact BlueMatt on freenode if something looks broken.
