[rules-users] Drools Fusion in JEE environment

Hi all, i am planning to use the Drools engine in the stream mode within an JEE application server. I have to process events of different users which can define their own rules. So I plan to instantiate a stateful session for each user and populate them with the user's rules. However, I am concerned how to manage the firing of the rules - which might be delayed by some time because of some rule statements (fire rule after having event A and no event B within 3 minutes). Spawning a thread for each session and calling fireUntilHalt is not an option in my opinion. I've found a solution where somebody uses a scheduler within the container to call fireAllRules at certain domain-specific intervals (e.g., every 10 seconds). I am wondering if there is a more clever approach. I am thinking of providing a callback that can be used by Drools to notify when it has to be "waked-up" again to fire the delayed rule.
