They *could* become a shared resource, however, if the client runs multiple
threads against the same session bean reference, which is quite common in
servlet applications....
The EJB Spec guarantees that only one method call at a time will be allowed
on any Bean, IIRC, so other callers will be blocked on any bean method until
the first method completes and returns.
