Sometimes Ctrl+C does not cancel

[mikedotexe]

I'm on commit hash 79f91aa5eb606a1fa453db18e4fcd5dc45fe0d8b and, after running the agent for about an hour, I tried cancelling it and it wasn't working. You can see the ^C in the logs here:

I'm quite sure I'm up to date with the latest code, so I think this issue persists. I believe it was addressed before but perhaps there's a new issue when it's more long-running.
