Each freshly allocated chunk must have both cinuse and pinuse set.
That is, each allocated chunk borders either a previously allocated
and still in-use chunk, or the base of its memory arena. This is

the oldest chunk (the next to be used, in our FIFO ordering)

is inserted, it is linked off the existing node using pointers that
work in the same way as fd/bk pointers of small chunks.
Each tree contains a power of 2 sized range of chunk sizes (the

half (0x140 <= x < 0x180) in the right subtree. This is, of course,
