                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 "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 thread factory to use to create worker
                threads.
