A reasonable idea, but I think that there is a bug:

> +      chunk_nread = cache_bread_1 (abfd, buf + nread, chunk_size);
> +      nread += chunk_nread;
> +
> +      if (chunk_nread < chunk_size)
> +        break;
> +    }
> +
> +  return nread;

If cache_bread_1() returns -1 for a read after the first chunk then 
cache_bread() will return one less byte than was actually read.  Hardly 
world shattering I agree, but it would nice to see this corner case 
handled correctly.

Cheers
