Directory premissions may vary depending on umask used.  If your 
umask breaks tests for you - you may try changing it while running 
tests.  It also shouldn't be important when running tests under 
non-privileged user.

I don't think this change should be added at all, and don't 
see how it's related to FreeBSD jails your patch says it's about.

AFAIR, multi-IP jails used to provide per-jail loopback 
addresses.  But may be I'm wrong here and mistaken with wildcard

As long as it's the only test affected we may consider it.
Sergey, could you please take a look?
