you CAN interrupt

        while do sleep 0; done

there is no need for exit, and it doesnt fix

        while do done

or

        while :; do :; done

if your shell needs something to not do.

as an aside, using while do as a simple loop and putting

        sometest && break

is a good way to NOT get tests wrong.
