> It looks too expensive to use memcmp to compare two buffers. Instead, the
> starting address and length/capacity would be good enough to use. Higher
> level codes relying on memcmp behaviour can be done in higher level.
> Update: memcmp should be avoided in Equal when comparing with the same
> Buffer. In other cases, it's still needed to know the content are the same or
> not.
