Static socket resources are handled *completely* wrongly. They're so
wrong that the best thing to do is to rip them out and let your dog
pee on them.
As for separating IO space offset vs static mapping, this will cause
major headaches for my replacement socket mapping code, which rather
spanners me for getting stuff into Linus this weekend. ;(
