1. Develop a small program that creates and starts one or more threads performing some arbitrary task.

2. Then from the main thread, wait for some time or a trigger and query the status one or more of the threads you have created.

3. Extend the example so that the main thread waits in a loop for a running thread to terminate, checking the status each iteration (this is called a busy loop).

4. Comment your code, all sections of the code should be clearly explained.
