[StarCluster] Terminating a cluster does not remove its security group (UNCLASSIFIED)

[Dustin Machi]

If the terminate command fails, then there will often be things left 
behind.  This often happens if you manipulate the security groups 
outside of start cluster and it fails to delete the security group. For 
example if you start a cluster and then add it's security group to 
another manually, it can't be deleted because that group is referenced 
by another.  This is just an example, but there are several places where 
terminate could fail.  These sometimes require cleanup before reusing a 
name again.
