The current implementation consumes about 3× the file size when uploading to S3 (tested with a 1 GB file, memory usage was ~3.2 GB). Downloading is even worse: s3proxy is consistently killed by the OS OOM killer when trying to download a 1 GB file from S3. At that moment the server had 5–6 GB of free RAM, and s3proxy consumed all of it.
With the changes from this PR, s3proxy consumes about 2× the file size for both uploads and downloads.
