I don't think you should see the problem in these terms.  You don't
have to select a task from the pool; the tasks select themselves as
they become available for a new job, e.g. each task would look like

loop
   Queue.Get_Next (Job);
   Process (Job);
end loop;

where Queue is a protected object and Get_Next removes a job from it
and passes it to the task. Of course, if there are no jobs in the
queue, it blocks until one arrives.
