this approach is good for small data, but with larger files with many
concurrent users this may eat up your memory, because the Stream buffers
the data there. In this case you can just create a Buffer and write it when
done. But i also prefer the tmp-file approach: no buffering and a mv is on
the disk is not that expensive.
