        Grief - but calling 'exec' is unlikely to leave the threads around of
the previous process in some unharmed state - surely it will just
terminate them all [ presumably that is what we want ;-].

        If not, a quick:

        if (!fork()) {
                // close all sockets
                exec (...);
        }

        Would presumably do what we want (?) :-) Hopefully we're not counting
on some configuration writer thread to write the config :-)

        Anyhow, if the fd limit is 256 it's hardly going to be a big hit
anyway, so no real problem.

        Thanks,

                Michael.
