 *    mcxRealloc is notable, for it *frees* memory and returns a NULL pointer
 *    if the newly requested block has size 0.  This must be so in order to
 *    allow routines to do their math and housekeeping. If they register the
 *    new block as having 0 bytes, then they need not and must not attempt to
 *    free it thereafter.
