More garbage is produced before gc, so the memory layout is worse.

Not when using `load-source-file-function':

      /* We are loading a source file (*.el).  */
      if (!NILP (Vload_source_file_function))
          Lisp_Object val;

          if (fd >= 0)
            emacs_close (fd);
          val = call4 (Vload_source_file_function, found, hist_file_name,
                       NILP (noerror) ? Qnil : Qt,
                       (NILP (nomessage) || force_load_messages) ? Qnil : Qt);
          return unbind_to (count, val);
