这样允许这一个服务线程去活动代表那个客户端线程来访问在服务上的对象，或者是使对客户端自己的对象的访问生效。
This allows the server thread to act on behalf of that client to access objects on the server or validate access to the client's own objects.
因为用户线程构造器中的代码仍然在访问线程的环境下运行，所以在构造用户线程时，我们还有机会从服务线程继承场所对象。
As the code in user thread constructor still runs in the caller thread's context, we have a chance to inherit a locale object from the servlet thread when the user thread is being constructed.
如果封装的代码使用大量的堆栈空间，只需要服务线程需要分配足够的RAM，客户端线程可以通过向服务线程发送请求来节省RAM。
If the encapsulate code USES a large stack area only the server thread have to allocate enough RAM, the client threads save RAM by just requesting the service to the server.
在讨论线程服务中，连接的资源表示形式的示例可能包括根讨论主题及其属性，以及指向为该主题提供的响应的嵌入链接。
In the discussion threading service, an example of connected resource representations might include a root discussion topic and its attributes, and embed links to the responses given to that topic.
异步完成令牌支持线程池，它允许服务在等待异步响应时释放线程，并将其放回到池中。
Asynchronous completion token supported thread pooling by allowing services to release threads back into the pool while awaiting asynchronous responses.
使用社交网络服务、论坛和讨论线程与其他博主建立联系。
Use social networking services, forums and discussion threads to connect with other bloggers.
等待数量和总等待时间：调用某方法或服务时，等待线程的实例数量和总占用时间。
Number of waits and total wait time: the number of instances and total elapsed time when the thread was waiting while invoking a method or service.
最后，由于消息到达的速度太快，系统无法支持登录服务中运行的线程数量。
Finally, the system could not support the number of threads running in the logging service as a result of the rate of message arrival.
当线程返回服务响应时，在中介流中继续执行。
When the thread returns with the service response, the execution continues in the mediation flow.
稍后，客户端运行的线程从该服务请求响应。
Later, the thread on which the client is running requests a response from the service.
未来，我们打算将不同服务的线程池组合为一个单独的工作管理基础设施，用于均衡负载。
In the future, we plan to combine the thread pools from different services together into a single work-management infrastructure that can be used to balance between these different workloads.
异步——使用者通过两个线程调用服务；一个线程发送请求，而另一个单独的线程接收响应。
Asynchronous - the consumer USES a pair of threads to invoke the service; one thread sends the request, then a separate thread receives the response.
线程还是比较耗费资源的，一个服务器上可用的线程是有限制的。
Threads are relatively expensive, and a limited number of threads are available on a server.
用户线程是服务来自客户机应用程序的请求的数据库服务器线程。
A user thread is a database server thread that services requests from client applications.
同步——使用者通过单个线程调用服务；该线程发送请求，在服务运行时阻塞，并且等待响应。
Synchronous – The consumer uses a single thread to invoke the service; the thread sends the request, blocks while the service is running, and waits for the response.
结束当前线程服务的执行。
消息侦听器服务中的线程池。
