As far as I understand, the test succeeds if there are no ordinary
files in one of the sticky directories that are owned by others. In
fact the test also succeeds if the first ordinary file that is owned
by somebody else is not writeable by all. After some iterations I had
to run `touch /tmp/.aaa; chmod og+w /tmp/.aaa' as root and then run
the test as a non-priveleged user to reproduce the result.

In fact, I was running the test as an ordinary user. If I try to run
this test as root I only get the following:

`.' is on an ufs partition and /tmp seems to be tmpfs.
