Aha, that is indeed what's happening.

There is no ::1 line in /etc/hosts on this machine.

I've checked this out on two different S10 installs (one fairly old, one
S10u3 (= 11/06)).  I didn't enable ipv6 when installing these machines,
or fiddle with it later.  If this is bustage then it's going to be very
common indeed, so it likely makes sense for the tests to code around it.
