> Today this uses the default implementation, e.g. for readInt(pos):
> {code}
> @Override
> public int readInt(long pos) throws IOException {
> slice.seek(pos);
> return slice.readInt();
> }
> {code}
> But this causes the bounds to be checked twice. Just like we did for MMap, we
> can provide a faster implementation that only checks once: yields ~30%
> speedup.
