Subject: Number of buckets is 1024 now Clean all torrents now only cleans one
 bucket at a time All torrents that are being worked upon in an announce are
 being cleaned on demoand torrent's peer lists now keep extra counts for seeds
 and peers to speed up scrape and announce Sync has gone for now. I will think
 up a new way to implement. The old one was way to slow.
