Traditionally, unix domain sockets were created mode 777; the mode was
also ignored. Later BSD releases have been changed to consider the mode;
when connecting (obviously, there's no "connect bit" so I'd assume they went
for read-write access).
When scuh changes were considered for Solaris, it was found that some software
depended on Solaris ignoring the permissions.
I think that the xnet sockets did get changed to honor the permissions.
