> S3 writes can be synchronous: when a part is uploaded, Write() will only
> return once the server has received the contents and responded "Ok".
> We may want to add a S3 option to issue writes in the background (e.g. using
> the S3 client's asynchronous APIs).
> Another possibility is to provide a general OutputStream implementation that
> backgrounds writes (this should be independent of BufferedOutputStream,
> though, because S3FileSystem already has its own buffering layer).
