Regression was introduced in 2fa2fa41c5.
In file download failed handler we suggest to try to load the file
once again to the same location. After some changes we started to
forget filename before failed handler. That resulted in large files
loading to memory instead of hard drive.
Add a precondition in FileLoader to prevent such bugs in the future.
