I am not experiencing this on very current i386 or pmax systems.

Only thing I can think of is...make sure your /etc is reasonably
current (some networking changes in /etc went through about a month
ago, and /etc is never automatically upgraded) and make sure your
/etc/hosts and /etc/resolv.conf are sane.

Make sure /etc/netstart has these lines:

# set the address for the loopback interface
ifconfig lo0 inet localhost

# use loopback, not the wire
route add $hostname localhost

Also make sure netstart isn't crashing out early on and preventing
that part of the script from executing.
