+ * The TCP out-bound tunnel is almost identical to the in-bound tunnel.
+ * We use MetisStreamConneciton for the out-bound tunnels too.  We call a different
+ * constructor than the in-bound so the MetisStreamConneciton knows that it is starting
+ * unconnected and needs to wait for the Connected event before putting it in the UP state.
