Question #1 is why is the exception happening? Question #2 is how to scp from the client to the server? Can I use sendRequest() to open a file and then Channel.write('some data') to send the client file contents?

This happens most frequently as a result of calling reactor.stop() more than once.
It'd be nice if the 2nd (and subsequent) calls to reactor.stop() raised exceptions synchronously, probably. It doesn't seem to be a very high priority change, though.
