Fast return from Java Activity Agent

Question

Hello,
long ago I had defined some workflows using the Java Activity Agent. But now I have to create a new flow with a lot of very short activities, and I want to return control to the workflow engine as fast as possible when they complete, without waiting for the next call to background processing. Is there any known best practice to achieve this? I have tried to enqueue calls to the background engine in my java classes, but this doesn't seem a solution.
Thank you in advance,
Antonio

Hello,
I didn't post my solution because it's very hackish, though it has dramatically improved my execution time.
But to answer your curiosity...
I have added a listener to the inbound queue, thus replacing the loop to call the background engine with calls synchronized with inbound messages. Additionally I call the background engine every 30 seconds, just in case, and so that the loop exit condition is checked.
So, here's my basic listener/background handler:
DECLARE
        q_agent sys.aq$_agent;
        wf_agent sys.aq$_agent := sys.aq$_agent(NULL,'OWF_MGR.WF_INBOUND_QUEUE',0);
        v_tab_agents DBMS_AQ.aq$_agent_list_t;
BEGIN
        v_tab_agents(1) := wf_agent;
       WHILE( < ANY CONDITION TO STOP PROCESSING ... > ) LOOP
         dbms_aq.listen(
         agent_list => v_tab_agents,
         WAIT => 30, /* in seconds, may be   DBMS_AQ.FOREVER */
         agent => q_agent
         owf_mgr.wf_engine.background;
     --    DBMS_OUTPUT.PUT_LINE('Date: ' || TO_CHAR(SYSDATE,'yyyy/mm/dd hh24:mi:ss' );
          END LOOP;
END;
