Files are now uploaded asynchronously, but this means if many files are uploaded and some are then removed from the list before submitting the form, the deleted files will remain in a temporary folder until deletion by a later process.
To avoid this, a process of cleaning (possibly together with cache) should be offered through the admin interface and as a cron task.
