Force use of 127.0.0.1 on *BSD systems

This is an attempt to see if I can make the tests pass on BSDs.  I
suspect that they configure the loopback device not with 127/8 but
something smaller: 127/24 or even 127.0.0.1/32. I don't have access to
a box to check and can't seem to find an answer on the net.
Release version 0.0.3_2 (2014-09-14)
