I'm also using `sinatra_sse` to wrap Sinatra's streaming facilities. I've noticed that, for every machine connecting to my server, each machine can only have 6 open connections at any given time, and Thin will stall any additional connections until one of those six are closed. I am experiencing this issue on both Windows 7 (running Ruby 1.9.3p327) and Mac OS X 10.8.3 (running Ruby 2.0.0p0). Due to the constraints of my application, I cannot have multiple Thin servers running. Additionally, I am not starting my application via Rackup, but rather I am invoking Thin inside an existing EventMachine reactor like so:\r\n\r\n```ruby\r\nEM.run {\r\n  @@thin_instance = Thin::Server.new ip, port, MyApp, signals: false, threaded: true\r\n  @@thin_instance.start\r\n}\r\n```\r\n\r\nAny ideas why this could happening? 6 seems like an arbitrary number for a connection limit."}}
