## Concurrency Notes ##
`ServerConn` is safe for concurrent access. What this means in practice is that
you can dial a connection to your FTP server, login, and pass around the
resulting `ServerConn` to multiple goroutines. However, this does not mean that
you can simultaneously upload or download multiple files. Because of limitations
inherent to the FTP protocol, there is a lock around these kinds of methods. The
user also needs to be aware that any call to `ChangeDir()` or similar will be
felt across every goroutine accessing that session. It is best to handle those
calls synchronously, eg immediately after logging into the FTP server.
