Correction.
The failure below is not on ext3, but on a loopback-mounted
ext4 file system.

The test detected that the current FS was ext3 -- and it's known
that this test is not useful on ext3 -- and since I was running it
as root, it creates a loopback ext4 file system on which to run the test.

However, other strange things are happening here.
I'm investigating.
