It may be that the problem that they are encountering is orthogonal
to the reconfiguration of the cluster.  In my experience, it is 
unfortunately the case when often nodes need to be dropped and restarted.
I don't believe *everything* works, but in light of the fact that
it is supposed to I will take better care to preserve test cases.
Test cases are difficult to reproduce, usually, on my own system
since they are relying heavily on client apps and data.
