Binary compatibility with what?

> There are many bugs related to the FTP variants and after taking several passes I've
decided to hold off for the time being. Most of the code either isn't thread safe or implements
concurrency in a manner that is difficult for me to understand what it is trying to do. FtpFileObject
synchronizes on the file system which creates a huge bottleneck and without understanding
how commons net works it isn't clear to me why this is being done the way it is. It almost
feels like someone just tried to make it thread safe by brute force. OTOH, SftpFileObject
doesn't synchronize on anything which looks problematic to me. But I have no familiarity with
jsch so I suppose I could not be understanding something.

at this point I think I'm ready to try again to release 2.0.
