Hm, you're talking about the "data_except" member of ssh_socket_struct?
From what I can tell that's a flag that gets set if we caught an error,
but (I'd hope) that the error also gets propagated back into the public
API for the call, where it can be caught by applications.

Is there an advantage to exposing that for applications as opposed to
just having them check the return values from existing API?  (My
application checks every return value)

Ok, it looks like ssh_socket_get_status() already gives you
SSH_CLOSED_ERROR in this case.

It looks to me like we close on any error, and further calls should
return errors.  

But if you think it'd be useful I'm happy to add it.
