When I said "What is the point of freeing them yourself," I was actually
saying "[. . .] yourself upon exit," since he said he wants to free them
upon exit himself. (Now I know that he wants to test for memory leaks.)
So for your explanation of memory leak, I would grasp onto this opportunity
to ask a simple question: Is this considered a memory leak?
char *buf = new char[100];
buf = new char[100];
Now I cannot use the first 100 char's I allocated. This would be a memory
leak in its simplist form, correct?

Great, if you want to reboot your mud constantly.

I doubt that he's having a problem with the MUD using too much memory when
everything works correctly.  More likely he's worried about a memory leak
somewhere in the code.  A memory leak is basically where you lose the
pointer
to some block of allocated memory, so you aren't able to free or reuse this
memory, and it just sits there.
Memory leaks usually come up with strings in ROM.  Since code dealing with
strings is everywhere, it's pretty easy for something to be coded
incorrectly
and lose a pointer to one.
