* Name: up_waste
*
* Description:
* up_waste() is the logic that will be executed when portions of kernel
* or user-app is polling some register or similar, waiting for desired
* status. This time is wasted away. This function offers a measure of
* badly written piece of software or some undesired behavior.
*
* At the same time this function adds to some IDLE time which portion
* cannot be used for other purposes (yet).
