sometimes Net::SSH will throw IOError when the server has closed the connection

[juliandunn]

This came up during some testing in the Veewee project: jedi4ever/veewee#499

Sometimes when the server terminates the SSH connection, an IOError is thrown rather than what I'd expect, which is Net::SSH::Disconnect. See this Gist for an illustration of the behavior.

Thanks for the report. Does sshd send a disconnect to connected clients when it shuts down though? As far as I know it doesn't. There's no way for Net-SSH to tell the difference between a network-related IOError and one resulting from sshd shutting down.
