How to use thread pool

ThreadPool* pool = createPool(4); // Intentionally ignoring the CORE * 2 + 1 rule.

    for(i = 0; i < 2; ++i) {
        Task task;
        task.deadline = 3; // in seconds.
        task.runnable = &echoTest;
        addTask(pool, &task);
    }

    for(i = 0; i < 10; ++i) {
        Task task;
        task.deadline = DONTCARE;
        task.runnable = &starve;
        addTask(pool, &task);
    }
