Jxcore并行添加新任务

Question

我正在使用jxcore并行执行作业。但是当我像下面这样测试的时候

var method = function () {
   var sleep = require('sleep');
   console.log("thread started", process.threadId);
   sleep.sleep(2);
   console.log("thread finished", process.threadId);
};

jxcore.tasks.addTask(method);
jxcore.tasks.addTask(method);
jxcore.tasks.addTask(method);
jxcore.tasks.addTask(method);

结果似乎只使用了一个线程：

thread started 0
thread finished 0
thread started 0
thread finished 0
thread started 0
thread finished 0
thread started 0
thread finished 0

我预计，它会创建4个线程并行启动。我怎样才能做到这一点？

尝试：

Function.prototype.clone = function() {
    var that = this;
    var temp = function temporary() { return that.apply(this, arguments); };
    for(var key in this) {
        if (this.hasOwnProperty(key)) {
            temp[key] = this[key];
        }
    }
    return temp;
};

var method = function () {
   var sleep = require('sleep');
   console.log("thread started", process.threadId);
   sleep.sleep(2);
   console.log("thread finished", process.threadId);
};

jxcore.tasks.addTask(method);
jxcore.tasks.addTask(method.clone());
jxcore.tasks.addTask(method.clone());
jxcore.tasks.addTask(method.clone());

或者：

var newmethod1 = method.clone();
jxcore.tasks.addTask(newmethod1);
jxcore.tasks.runOnce(newmethod1);
