The satellite data of the ``ByteBuffer`` cannot be modified in
any way and stay thread safe in the presence of concurrent readers.

This implementation is simple and does introduce an allocation, however
without it multiple readers will quickly and continuously encounter
``IndexOutOfBoundsException`` exceptions.

An alternative, but possibly more controversial, implementation would
be to use ``Unsafe``.  Using ``Unsafe``, it's possible to do an
array copy with a provided buffer index.
