Comment 2 for bug 1742729

Usually the service automatically deletes a blob instance if there was an error during uploading process. For sure we can't guarantee this behavior always, because in some cases mysql db doesn't respond in time.

I agree that we must prevent such situations and allow users to delete blobs with 'saving' status.
But we must do it right and exclude the situations when malicious users will reupload their data, and therefore clog the storage.

My proposal is to add a new policy for deleting blobs with saving status and let only operators perform this action.
