/* 
 * WHAT THIS EXAMPLE DOES
 * 
 * We create a pool of 4 threads and then add 40 tasks to the pool(20 task1 
 * functions and 20 task2 functions).
 * 
 * task1 and task2 simply print which thread is running them.
 * 
 * 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.
 *
