I just found this issue by:

1. node with image field, ajax upload a image
2. close or refresh the node add page without saving
3. run cron and clear cache, but the images still existed in container
4. audit also doesn't help
5. the image is orphaned in container!

seems those temporary files always failed to be removed during cron.

storage api seems has no checking on temporary files, is this missing or just a core bug that can't delete temporary files served external?
