Overview

When you reboot a remote machine with sudo reboot now for example, some machines come back up within :20 seconds. Others, it might take a minute or two. Well, instead of hitting up arrow, Enter and seeing:

ssh: connect to host server.example.com port 22: Connection timed out

Instead of using ssh user@host, this function is sshw user@host, as-in "SSH Wait". You'll see a message like this:
