All sockets do - well, almost all; it is possible for a socket to exist
without any process having a file descriptor referring to it, but it's
rare.  (The only examples I know of are sockets in transit in
SCM_RIGHTS messages, when the sender has closed its descriptor and the
receiver hasn't received it yet, and a few kernel-internal uses such as
the NFS client.)
