You're right. For threads not hanging you could monitor the execution time of a evaluation thread and suspend a hangung thread using the java debugger interface (http://java.sun.com/j2se/1.5.0/docs/guide/ jpda/jdi/). Perhaps VisualVM can throw in some technology to monitor actual runtime of the thread and and memory consumption. However this is a rather fragile topic for java. Spawning some additional jvms will probably do better. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
