What about a CURL Option for disabling this for WS-FTP servers?
I'm not sure if that fits your philosophy or not ... but for people
trying to connect to a WS-FTP server with client and server
certificates enabled it would be a blessing.

Eeh. I need to take that back. I've read up on the topic and there
should
1) never be any harm in trying to re-use a session and 2) a session can
very
well be used on more than one connection.

So, re-using the session like this makes the data connect phase a lot
faster
and I now instead claim that this is "just" a bug in the server end.
