Hi Poul-Henning,

I went thru the man pages and there is indeed no such guarantee.
Neither do the Linux man pages.

So I'm contemplating what to do with the test. It is sort of hard to
determine if the Ceph tools somewhere expect this ordering. But for the
time being I think I'll just disable the test.
