That's also true, I believe, if one runs a torrent client (or whatever) on a VM that connects only through a TCP-based VPN service (anonymous, paid with mailed cash) which connects through Tor.  The VPN will handle all traffic from the VM, whether it's TCP, UDP or whatever.  That's not the case if one routes Tor through a VPN, by the way.  However, one can use VPNs on both ends of Tor, without much additional penalty.  But I can't imagine why anyone would want to torrent through such a kludge.  Using multiple nested VPNs is argumentally anonymous enough for most purposes, is much faster, and doesn't waste Tor's bandwidth.
