New description:

 Travis recorded a failure in `test_util.FileUtil.test_disk_stats`, while
 running under python2.6, against my "2023-caution" branch (git revision
 1a07dfdedef4747784ad1798542a2f4c0b9c4be3). I can't think of any reason
 that ought to behave differently than the trunk revision
 6a38a3c54e0846dea625f5af0a4d365f9368acf6 .

 This test didn't fail for me on OS-X under python2.6 .
