/*
* 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.
*
