Re: Error creating ebsimage. (ver 0.92)

Hi Paolo,

My apologies for the delay. From the output you sent it's clear that the
ebsimage command completed successfully, however, for some reason
paramiko threads are not being shutdown before the main thread exits. I
believe this is a bug in paramiko but it could also be a bug in
StarCluster. In any event I'm unable to reproduce it...

Is this reproducible for you? I've found others having similar issues
with paramiko even in the simplest cases where they explicitly close
paramiko connections before the main thread closes:

https://github.com/robey/paramiko/issues/17

Also, which Python version are you using? The issue above mentions it
happens on 2.7.2 but not on some 2.6 versions...
