Comment 16 for bug 431975

I can attest to this in Lucid with ecryptfs encrypted /home/user. I'm not sure about Transmission or Vuze, but in rtorrent, there's a way to save the machine and still have large torrent downloads; add this to your ~/.rtorrent.rc:

split_file_size = 8G # or 4G or 3G, depending on your system (mine is good at 3G)

And then when the torrent is completed simply run 'cat file_1 file_2 ... > file_x' and then you're good to go.
