--------------------------------------
+1 This looks good to me. Can you run test-patch on it please?
> TestTrackerDistributedCacheManager should be up-front about requirements on

> TestTrackerDistributedCacheManager will fail on a system where the build
> directory is in any path where an ancestor doesn't have a+x permissions. On
> one of our hudson boxes, for example, hudson's workspace had 700 permissions
> and caused this test to fail reliably, but not in an obvious manner. It would
> be helpful if the test failed with a more obvious error message during
> setUp() when the build environment is misconfigured.
