We should do this, possibly one module at a time, then we can try to add new syntax-check rules forbidding malloc/realloc. Also potentially we could hook up memory checks at runtime with the macro, if we need to in the future. +1 for applying this now, then we can fix one module at a time later. we don't need to grow a gigantic patch.
