The disk cache is still relativly ineffective compared to, say utorrent.3.0.0.26473 in that I get essentially the same number of writes to the disk as I get writes to the cache... At least some of the ted torrents appear to point to different files than the ones from which the torrents were created. I'm going to add some verification that gives a better error in utorrent. For example, the sarah kaminsky torrent claims to be 98303105 in the torrent, but the file on the web server is 98419885 bytes long. I manually downloaded the first piece just to be sure the file isn't just truncated, but the hash is different.
