clarification on "victim" symbol

[last-byte]

I've noticed it's not very clear, at first, when you use the name "victim" in the first chapters of the book referring to the malloc-ed chunk. I had to search a bit to find out you have used this name with the same meaning of the one used in the black hat's paper you referenced in the first pages. I think it would be better if you added a paragraph explaining victim = malloc(0xbadc0de) or something like that.
