-   One solution for this could be to define SYSTEM_MALLOC in configure,

-   It is possible to completely override the malloc implementation on

-   library and setting the MALLOCTYPE environment variable to point to
-   that shared library.
-
-   Emacs currently calls xrealloc on the results of get_current_dir name,
