- This is much like the Task we've used in the past for implementing a thread
- pool. This time, however, I've made the Task an element in a singly-linked
- list. As the svc() method finishes the process() on a unit of work, it
- will enqueue that unit of work to the next_ Task if there is one. If the
- Task does not have a next_ Task, it will invoke the unit of work object's
- fini() method after invoking process().
