[Starcluster] StarCluster Saving State?

[Austin Godber]

After I browsed the code I was under the impression that starcluster 
stored no local state beyond the config file.  It had appeared that 
everything was queried from EC2 itself (for instance listing clusters).

Is this correct?  I am getting a KeyNotFound error for a key that I had 
deleted from prettymuch everywhere.  NOTE: I am doing weird stuff e.g. 
trying to use starcluster as a library.  So I may be encountering 
strange conditions.
