Sometimes this is true, sometimes not. It depends on how many blocks of memory you allocate and for what purposes, I think. For short-lived programs it can make sense that some things are never freed (they will be automatically freed when the program terminates), but still there might be some things which should be managed anyways. It also depends on the program, and on other things.
