EJB 2.x has the notion of an EJB "Home", which can destroy bean instances (sessions) without invoking any business logic. CDI demands the same "backdoor" removal from EJB3, and we must provide a remotable, replicable mechanism.

Additionally, SFSB injection is not a great idea. Sessions can time out or be removed by the container entirely, leading invocations upon the injected reference to throw NoSuchEJBException. Instead we can leverage a "SessionManager" to be injected, which may create/destroy bean instances as instructed by the bean provider.
