Fine by me.

Will you approve the patch if next_bin and prev_bin are changed like so?

#define next_bin(b)    ((mbinptr)((char*)(b) + 2 * sizeof(main_arena.av[0])))
#define prev_bin(b)    ((mbinptr)((char*)(b) - 2 * sizeof(main_arena.av[0])))

BTW, who has approval authority for malloc.c changes?
You only?  Uli only?  Both of you?

Thanks,
Greg
