/* to free memory, you just free the first "nalloc" members of the      */
/* "allocated" array.  This should be fairly bulletproof, except that   */
/* realloc() calls could mess you up.  For each pointer, allocation     */
/* should be done in one place only, then left well alone.  Memory that */
