  Clearly that makes for cleaner code, and more importantly safer.
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.
