朴灵老师，多进程中，如果创建子进程之后server.close()，就不能再次fork进程了

for (var i = 0; i < cpus.length; i++) {
  createWorker();
}
server.close();

var server = http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('handled by child, pid is ' + process.pid + '\n');
  throw new Error('throw exception');
});

子进程挂掉之后，父进程的监听已经关闭了，此时如何才能重新fork进程了

什么版本。
