There is never a need to free memory before exiting from a program.
All work being done to free up the memory, coalesce memory blocks,
list memory blocks in a free list, and so forth is completely
unnecessary power that is wasted.  Think of the heat and battery life
wasted by doing this across zillions of devices.  Upon exit all
resources are freed as the program evaporates.
