> 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.
