SSH: Lock up on network lost

[tebrown]

Describe the bug

I was ssh'ing into a remote machine. Just as it was 'Starting Bash...', I lost network.  All my sessions locked up, including the ones connected to the local machine. I had to force quit the app.

To Reproduce

Steps to reproduce:

1. ssh to remote machine
2. Just as it is trying to start bash, disable wifi or disconnect network
3. Terminals all lock up

Expected behaviour

If network goes away while establishing a remote connection, it should simply error out and return back to the local session
