SFTPClient.get leaves file open after error

[flxkid]

Testing file transfers on a GPRS modem which can drop the connection sometimes. If the connection is dropped during a file transfer using SFTPClient.get an exception is generated, but the local file that was being written to is left open. I need to schedule the file for retry and delete the partially downloaded file, but I can't because it is still open. I think the get method needs some error handling so that it can cleanup after itself and then pass the exception up for the application to handle.
