Freeing

Is there any real point in freeing memory these days? And I don't mean freeing memory for things that constantly grow and shrink in size. I mean freeing that one array that you malloc at the beginning of the program and you need it until the end of the program. What is the benefit of freeing it when it will be automatically freed by the operating system?

Explain this then.

b:\>cat  memory.c
#include <stdio.h>
#include <stdlib.h>

main(){
    fwrite(malloc(0x100),1,0x100,stdout);
}
b:\>gcc memory.c -o memory && memory|hexdump -C
