As a result of the last caveat here, I recommend either restarting the
node with the join_ring as false or using iptables to firewall off
ports 7000 and 9160. If you want to be sure that you have stopped
write activity right now, nuking these ports from orbit is the only
way to be sure. disablethrift/disablegossip as currently implemented
are not sufficient for this goal.
