> The S3AInputStream reacts to read(byte[]) failure by reopening the stream, just as for the single byte read(). We shouldn't need to do that. Instead just close the stream, return 0 and let the caller decided what to do. 
> why so? 
> # its in the contract of InputStream.read(bytes[]),
> # readFully() can handle the 0 in its loop
> # other apps can decided what to do.
