[StarCluster] poor behavior from addnode

[Cedar McKay]

If I try to use addnode to add multiple clusters (see below), and one fails to launch because I've already exceeded my max  instance number, the script will crash, yet some of the nodes will boot up. But it will boot without being integrated into the cluster. 

Also, is this even the proper venue for reports like this? Do the creators even read this list? Or should I be submitting bug reports?

Thanks!
Cedar
