You have a socket open to a remote machine, and on the far side you take down the interface, before the program you're running on the far side exits. I'm not at all sure what that does with existing connections, and whether ssh will eventually time out. It certainly means that the packets to cleanly close the connection won't propogate from the remote sshd to the local ssh.

What happens when drop the remote interface from the (local) command line? Does ssh exit, or does it hang?
