Yep, IPV6_V6ONLY is set to true by default, where as it is false
by default on Linux, however, .....

This code is not supposed to be relying on IPV6_V6ONLY. The testSocketTCPAccept
method is supposed to create multiple listener sockets. We passing NULL as the
listen address, which means we are supposed to get two sockets, one listening
on IPv4 and one on IPv6. So the comment is right about FreeBSD being different
but that situation should not apply to this test AFAIK.
So I'm wondering why it hasn't listened on both sockets...
