I created a sample app using Puma and Celluloid to work through similar troubles I was having with Sinatra's streams and Puma. If it helps, it's here: https://github.com/sdeming/cellfun https://github.com/sdeming/cellfun. This does not use EventMachine, depending instead on Celluloid. I work primarily in JRuby and EventMachine has always tripped me up.
