* This demo shows how to create a static thread and how to terminate it

* A GTimer is used to termiate the thread.

* Note: The GOS API does not provide any function to terminate or kill a thread
* as not every operating system allows it to terminate a thread out
* from another one. Therefore, we use the parameters to implement a
* "fall over the edge" algorithm.
