We can't use anything external -- that'd fail a lot more than using
(system-name).

But we should just disable this test if (system-name) doesn't resolve.
That should be easy enough to check for.  

(network-lookup-address-info (system-name))
=> ([127 0 1 1 0])

So reasonable values here would be 127 as the first octet on ipv4...
