The instance fields of the singleton will not be globally unique. Because several VMs are involved for what appears to be the same object, several singleton objects might be brought into existence.
原因在于多个虚拟机都可以涉及到相同的单实例类，这些单实例对象可能会同时存在于上下文中，从而导致这些单实例对象并不是全局唯一的。
The first element simply checks for the existence of a Machine instance in the working memory.
第一个元素只检查工作内存中是否存在一个Machine实例。
Some instance objects are themselves classes; and all classes are instances of a corresponding metaclass. Even classes only come into existence through the instantiation mechanism.
某些实例对象就是类本身，并且所有的类都是相应元类的实例，甚至类也只能通过实例化机制生成。
Represents an event that the SQL workflow instance Store raises to notify workflow hosts about the existence of runnable instances in the persistence database.
