Replying to myself - after quickly reading the code...

StarCluster uses Paramiko instead of executing ssh, so wrapping around a long latency ssh script won't work.

And there are quite a lot of discussions about issues with multithreaded programs that call Paramiko -- just google: Paramiko+multithreading
