Is using the 'online' event here instead an option?

@cjihrig I’ve added that but kept the timeout, it still seems to make this fail more reliably locally (with the node master executable).

w.on('error', common.mustNotCall());
w.on('exit', common.mustCall((code) => assert.strictEqual(code, 1)));
} else {
while (true)
vm.runInNewContext('');
}
