SO_KEEPALIVE?

SO_KEEPALIVE just tries to prevent one end from closing a connection that has been idle for too long under "normal" operation. The problem we're trying to detect is when the other side of the connection drops off silently so we don't waste time *writing* data to the connection. This is an error condition, SO_KEEPALIVE won't help AFAICT. Jon
