/**
 * This script deletes files that were not properly uploaded.
 * 
 * Files can remain in an invalid status for two reasons: 1) a user abandons
 * a document or comment after uploading files; or 2) a chunked upload is
 * aborted without the server having any opportunity to clean it up.
 * These files can obviously take up a lot of disk space. In order to prevent
 * them from accumulating too much, you should run this script at least once
 * every few days.
