[ruby-core:57669] Re: [ruby-trunk - Feature #8985][Open] xwillfree - promise to free memory

Ah, it is synchronicity.

I have another idea to approach for it.

how about another version of ruby_xfree() and ruby_xrealloc() to passing
2nd argument, which is passing same information pasing to xwill_free().

  ptr = xmalloc2(100);      /* allocate 100 byte */
  xrealloc2(ptr, 100, 200); /* reallocate 100 to 200 */
  xfree2(ptr, 200);         /* free 200 byte */

Doing same objective. but reduce one function call. I like this approach.
