To facilitate a clean coordinated shutdown, create a verb so that a termination can be done
and know when it is completed. Only allow for the 'special' case of 'skipauth', where unix domain
socket connection is in hand and only root or the service owner can access.
ssl wrap prior to accept causes accept() to be too complicated to stay in the
persistent thread and makes key changes require restart to pickup. Call
the wrap_socket within the dedicated client thread so that it gets up to date
at the right time and picks up certificate changes in a timely fashion.
