crictl behavior:

# sleep 1000
sleep 1000
^C
e2e-test-lantaol-master ~ #

docker exec behavior:

e2e-test-lantaol-master ~ # docker exec -it 2ccc5ed91407 /bin/sh
# sleep 1000
^C
# exit
e2e-test-lantaol-master ~ #

This seems like a pretty involved ticket. I was reading up on how kubectl exec does this and it sets up and manages its own ptys. It captures interrupts, but does depend on the docker library

Did you have any thoughts on how you'd like this to be implemented?

@chuckha I think it is fine to use a docker library. :) Would you like to send out a PR?

BTW, I found that this can cause exec process leakage for containerd, I haven't tried docker yet. Just note it here.
