With Herbert help, we have figured out what is going on. Some versions
of some OSes require /32 subnets for aliases on public network
interfaces. Recent FreeBSD versions are an example. While Polygraph
supports arbitrary subnets, the problem was that the PolyMix-4
addressing scheme had strict checks which prohibited such settings to
avoid a misconfiguration.

A patch that fixes the problem is attached. With this patch, Polygraph
warns but does not quit if an explicit subnet violates PolyMix-4 rules.
