.SS Abstract sockets
Socket permissions have no meaning for abstract sockets:
the process
.BR umask (2)
has no effect when binding an abstract socket,
and changing the ownership and permissions of the object (via
.BR fchown (2)
and
.BR fchmod (2))
has no effect on the accessibility of the socket.
Abstract sockets automatically disappear when all open references
to the socket are closed.
