Does the server have to maintain anything but a time-to-die timer?
When the server is created, the timer is set to some suitable value,
and the lease renewal code could look something like:

void Server::renew (unsigned int n_secs)
{
    time_to_die = MAX (time_to_die, n_secs);
}

This should guarantee that the server never dies within the time frame
that a client has requested it stays alive.  When the timer expires,
the server can safely commit suicide.
