-/* 
- * This is just an example on how to use the thpool library 
- * 
- * We create a pool of 4 threads and then add 20 tasks to the pool(10 task1 
- * functions and 10 task2 functions).
- * 
- * Task1 doesn't take any arguments. Task2 takes an integer. Task2 is used to show
- * how to add work to the thread pool with an argument.
- * 
- * As soon as we add the tasks to the pool, the threads will run them. One thread
- * may run x tasks in a row so if you see as output the same thread running several
- * tasks, it's not an error.
- * 
- * All jobs will not be completed and in fact maybe even none will. You can add a sleep()
- * function if you want to complete all tasks in this test file to be able and see clearer
- * what is going on.
- *
