------------------------------------------
132 is node1
133 is node2

> Playing with 0.7 nightly (today's build), I setup a 3 node cluster this way:
> - Added one node;
> - Loaded default schema with RF 1 from YAML using JMX;
> - Loaded 2M keys using py_stress;
> - Bootstrapped a second node;
> - Cleaned up the first node;
> - Bootstrapped a third node;
> - Cleaned up the second node;
> I got the following ring:
