> Currently, S3AInputStream.close() calls S3Object.close(). But,
> S3Object.close() will read the remaining bytes of the S3 object, potentially
> transferring a lot of bytes from S3 that are discarded. Instead, the wrapped
> stream should be aborted to avoid transferring discarded bytes (unless the
> preceding read() finished at contentLength). For example, reading only the
> first byte of a 1 GB object and then closing the stream will result in all 1
> GB transferred from S3.
