Intermittent testing slave failures

Just as a heads-up, we are currently trying to test a more manageable way to roll out new testing slaves via a virtual machine instance and inside Amazon EC2 instances. However, we are still having problems debugging, and as a result, the test bot is intermittently reporting failures to the issue queue (esp. be leery of "Failed to install HEAD.")

If your patch is mistakenly marked code needs work, we apologize. Please mark it back to "needs review" and request a re-test from the link in the test status. We hope to have these problems ironed out shortly.

If you have Linux experience, we would love you to to drop by #drupal-infrastructure to help us get things running smoothly again. :)
