线程对象不会立即返回并且程序挂起

我有一个线程对象，大部分时间都运行得很好。
线程不会立即返回并且程序挂起。
当我暂停程序并查看执行流程时，看起来数据流不一致。
我可以翻过线并看到公式输出的值，但它输入的输入将为空。
我一直非常谨慎地控制流程，因为与用户对象不同，线程对象似乎是不可原谅的。
我也只在Thread对象中使用嵌入式函数和唯一变量。
我已经遇到并解决了这些问题。
所以我想知道的是：我怎样才能检测到这个挂起并退出线程？
（就像一个超时引脚）我需要这个程序自动运行。

     以下为原文

  I have a thread object that works fairly well most of the time.  Every now and then the Thread doesn't return and the program hangs.
When I pause the program and look at the execution flow, it looks like the data flow is inconsistent.   I can hoover over the line and see the value of the output of an formula but the input that it feeds will be empty.

I have taken great care in controlling the flow since the thread objects seems unforgiving, unlike user objects.  I also only use embedded functions and unique variables inside the Thread Object.  I've already ran into and solved those issues.

So what I'm wondering is: How can I detect this hang and Exit the Thread?   (like a timeout pin)

I need this program to run autonomously.   

Thanks
Randy
