#11233: AWS S3 upload (backblaze-comatible S3 api) doesn't work with files larger

 When using the AWS-compatible backblaze S3 endpoint as in their docs, it
 seems that small files upload fine and fast, but large files stall. The
 upload never starts, there's a message about "initializing large file
 upload" but then nothing happens anymore.
 The download can't be stopped or removed, only quitting Cyberduck brings
 it back into a working state (file upload still fails).

 Cyberduck is used as example integration app in the backblaze docs:

 I'm not sure if that's an issue with CyberDuck, Backblaze, or their S3
 integration, but since Cyberduck goes into a broken / unstoppable state
 there's at least something wrong here.
