I have (and have previously posted) prototype code to do c/r of open
sockets, ignoring some things like updating timers and such.  It looks
rather similar to the existing UNIX bits, and is even easier in some
ways.

One particular use case is only migrating listening sockets and
allowing the connected ones to be reset upon restart.  That enables a
bunch of things like apache, postfix, vncserver, and even sshd.  I
will pull the listen-only bits out of my current patch, scrape off a
little bitrot, and post them in a few days.
