                A thread pool executor with an unbounded queue.  Such a thread pool has a core size and a queue with no
                upper bound.  When a task is submitted, if the number of running threads is less than the core size,
                a new thread is created.  Otherwise, the task is placed in queue.  If too many tasks are allowed to be
                submitted to this type of executor, an out of memory condition may occur.

                The "name" attribute is the name of the created executor.

                The "max-threads" attribute must be used to specify the thread pool size.  The nested
                "keepalive-time" element may used to specify the amount of time that pool threads should
                be kept running when idle; if not specified, threads will run until the executor is shut down.
                The "thread-factory" element specifies the bean name of a specific threads subsystem thread factory to
                use to create worker threads. Usually it will not be set for an EJB3 thread pool and an appropriate
                default thread factory will be used.

                The EJB3 spec mandates that the invocations on remote interfaces of a EJB, use pass-by-value

                The pass-by-value attribute of this element can be used to switch that behaviour to pass the parameters
                by reference (and skip the serialization/deserialization step). Setting the pass-by-value to false will
                return in pass-by-reference semantics.
