send-off works by submitting a Runnable to a newCachedThreadPool. http://stackoverflow.com/questions/11316737/managing-agent-thread-pools-in-clojure
A Runnable sent to a thread pool will have exclusive use of that thread until it completes; therefore, greater concurrency can only be achieved by more threads, and 10k connections will need 10k threads. I don't know much about asynchronous IO implementations in Clojure, but agents probably aren't what you want.
