This is a guess on my part, but I would say that this might be due to the
behavior of malloc and Mac OS X's implementation of it. When the os increases
the size of an application's heap (where dynamic memory comes from) it doesn't
necessarily reclaim that memory once free is used. Instead, it may still be
allocated for that application's heap even though it is not in "use" and tools
such as top or ps will report it as such.

Perhaps someone who has more knowledge of memory management on OS X can confirm
this for me.
