A routing loop detection method called RMLD was proposed, which can quickly detect the routing loop in the second layer by using a kind of special RM cells.

提出了一种路由环检测方法，称之为RMLD。它通过使用一种特殊的RM信元可以在第二层上快速检测出路由环。

But this is a horrible approach because this thread will need to busy-loop to detect a change in a reasonable time frame.

这是一种非常可怕的方法，因为线程需要在合理的时间范围内频繁地循环检测变化。

For example, code that might go into an infinite loop, or otherwise use excessive resources, must be wrapped in testing code that will detect such eventualities.

例如，必须在专门的测试代码中捕捉到占用大量资源的无限循环代码。

If you detect the makings of an endless loop that can feed back onto itself, creating what might be called a virtuous circle and ultimately a more virtuous society you are getting the idea.
