usewithtor + irssi + ssl = "Socks version 22 not recognized"

Set up your ~/.irssi/config with

servers = (
  {
    address = "irc.oftc.net";
    chatnet = "oftc";
    #port = "6667";
    port = "6697";
    use_ssl = "yes";
    # ssl_cert = "~/.irssi/certs/[NICK].pem";
    # ssl_verify = "yes";
    # ssl_cafile = "~/.irssi/certs/CAs.pem";
    autoconnect = "yes";
  }
);

and then run

usewithtor irssi

Your Tor client will log something like

Jan 27 17:43:52.000 [warn] Socks version 22 not recognized. (Tor is not an http proxy.)
Jan 27 17:43:52.000 [warn] Fetching socks handshake failed. Closing.

and your irssi will complain with something like

18:06 -!- Irssi: Looking up irc.oftc.net
18:06 -!- Irssi: Connecting to irc.oftc.net [140.211.166.64] port 6697
18:06 -!- Irssi: warning SSL handshake failed: Connection reset by peer
18:06 -!- Irssi: Connection lost to irc.oftc.net

What's happening behind the scenes is that your irssi is attempting a connect, getting an einprogress (presumably since it's non-blocking), sending the ssl handshake right then, and then later torsocks tries to inject the socks handshake. Oops.
