Run a CLI command repeatedly until it fails. If it never fails, it will continue running indefinitely. If it does fail, it will exit with the same error code as the command being run. I wrote this to use when debugging flaky tests, but I am sure you can use your imagination for where you can apply this.
This is a CLI tool and cannot be used a require module.
