Good to hear. We don't pull eventmachine in directly, only indirectly via thin. I am on thin 1.2.11, as I suspect most of the other devs will be. With Marios' changes to the gemspec, the most tested versions of each gem are noted in server/deltacloud-core.gemspec. Gems can be installed from that with 'bundle install'. Details of that will go up on the website real soon now. David
