i'm not a COM+ guy but doesn't this have a lot to do with COM+ objects being
stateless. when you call a method on COM+ object, that object is activated
(created or fetched from the pool), run, and then deactivated (destroyed or
returned to the pool). In the EJB's more stateful model this restriction is
unworkable, but in the COM+ stateless model it's less of an issue. They
could have done it but probably spent more time doing other stuff...
