         * Generally thread-safe functions (though not on OS X) unlike
           gethostbyaddr/gethostbyname.
         * The interfaces are not totally compatible (e.g. no aliases data
           available, different error codes, etc). Try to make this change as
           transparent as possible.
         * Clean up old CMUCL compability cruft
         * Delete the obsolete documentation generator
         * Add a little extra documentation on the name-service to the manual
