 * Just an example to remind that its futile to free memory in the child
 * allocated by the parent to avoid taking a break COW perf. hit. 
 * Makes sense only to free large chunk sizes in the child. Smaller chunk sizes
 * aren't really trimmed by malloc and only end up causing perf hits with 
 * break COW pages (copy on write) when freeing in the child.
 * A break COW is when free results in malloc lib. touching the freed chunk 
 * of memory resulting in a write protection page fault for the child that ends up 
 * unmapping the shared page table entry and then maps a writable page copy to the child. 
 * The net effect for RSS(resident set size) is the same as in the parent but
