There is no point calling free() just before exiting. The OS will clean
up for you.
There are no leaks, but there are two points:
- as a reminder that things were malloced and will need
to be freed if this code is reused elsewhere
- the valgrind(1) leak checker will be happier and
complain less about "possible leaks" or whatever it calls it
