I don't think that primitiveSocketLocalAddress is broken. It correctly answers
the address associated with the local host name, which is not necessarily the
same as the address associated with the name 'localhost'.

The update that you did in NetworkTests-topa.38 looks like the right thing to
do.  It uses the address associated with the name 'localhost', not the address
associated with the local host name, and that would be the intended behavior
for the tests.
