Problem Description

While the ^C behavior in mongosh is much nicer than in mongo, it's too easy for auto-repeat to kick in, issue more than one ^C, and exit the shell – thereby negating this nice new behavior.

Steps to Reproduce

Hit ^C twice or more, shell exists.

Expected Results

^C just prints "use ^D to exit"; or even does nothing like in ipython. But does not exit the shell.

Actual Results

Shell quits.
