Given that RMI-IIOP does not support distributed garbage collection (unlike RMI-JRMP), do I need to do something explicitly to GC beans, or is it magically handled by the EJB framework?

(The lack of distributed GC was noted in the "EJBs from a critical perspective" article, http://www.techmetrix.com/lab/trendmarkers/tmk1299/tmk1299-2.shtml)
