 ## Process and Thread Model
 An application exclusively uses an independent process, and an ability exclusively uses an independent thread. An application process is created when an ability is started for the first time, and a thread is created for this ability too. After the application is started, other abilities in the application are started, and a thread is created for every of these started abilities. Each ability is bound to an independent JSRuntime instance. Therefore, abilities are isolated from each other.

 ## 进程线程模型
 应用独享独立进程，Ability独享独立线程，应用进程在Ability第一次启动时创建，并为启动的Ability创建线程，应用启动后再启动应用内其他Ability，会为每一个Ability创建相应的线程。每个Ability绑定一个独立的JSRuntime实例，因此Ability之间是隔离的。
