请您中译英,各位大侠请进(100分)

想用英文发个邮件,高手请帮忙,以下是内容:
您好,我参照您的代码做了一个demo在本机上进行测试,启动多个客户端用timer控件每隔半秒向服务端发送数据请求,随着并发性的不断提高,这时,服务器端的线程数持续增加,
当逐个关闭客户端后,服务器端的线程数并没有一一free,就是说非持久对象没有自动free,
请问是什么原因? 期待您的回复! (clients and server在同一台机子上)
谢谢

Dear Sir(xxx),
On the basis of your code, I compile a demo and test it on my computer. Several clients are launched and send data request every half second with a TTimer components. With the increase of comncurrence, the threads on the server side increases too. However, when clients are closed one bye one, the threads are not released one by one, ie, non lasting (?) object is not released automatically. What is the cause for this? (Note: the clients and the server on the same machine)
Looking forward to hearing from you.
Regards and Best wishes.

Yours Sincerely
