This sequence of evaluations ends in the REPL hanging: 1:1 user=> (.. Runtime (getRuntime) (addShutdownHook (new Thread shutdown-agents))) nil 1:2 user=> (def agent-99 (agent "Secret agent (99)")) #'user/agent-99 1:3 user=> (send-off agent-99 (fn [a] (println (str "In agent: " a)))) In agent: Secret agent (99) #<Agent clojure.lang.ag...@5b0668> 1:4 user=> (await agent-99) nil 1:5 user=> CTRL-D [ Hangs here. CTRL-C gets back to shell prompt. ] Randall Schulz --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
