Relay - Blackboard Economics

[Gordon Vidaver]

Hi,
         It's the responsibility of the client to remove them from 
the blackboard if they are no longer needed.  The relays will 
accumulate unless explicitly removed.  You should be able to see this 
if you have the "tasks" servlet loaded 
(org.cougaar.planning.servlet.PlanViewServlet) and browse to the 
receiving agent (e.g. 
http://localhost:8800/$YOUR-RECEIVER-AGENT/tasks).  If you look for 
UniqueObjects, you should see the thousands of relays that have been 
received.  If you don't need to keep them around, the client code can 
publishRemove them from the blackboard.
