/*
* The only purpose of this class is to hold onto an instance of
* FtpClient to prevent the FtpClient from being garbage collected.
* If the client gets collected it will close the command stream
* which will cause the remote ftp daemon to close its outputstream
* which will cause and EOF on this inputstream on our end.
*
* The real answer is to re-architect all this stuff to not open an
* ftp connection each time the user needs something from the remote
* side. The other correct thing it to totally ignore all the ftp
* client stuff and just use the ftp proxy stuff in the CERN HTTP
* server.
