Do any machines *not* have IPv6 stacks installed these days?

They may not have IPv6 connectivity to the outside world, but all my 
Solaris, Linux, and Windows boxes have IPv6 stacks installed by default.

So testing for an IPv6 loopback would still say "go for it."

Now, testing for IPv6 connectivity might turn a temporary failure into a 
permanent one, which is not good, it would probably be better for the 
IPv6 failure message to say "IPv6 connection failed, trying IPv4."
