<Not Available> and [Thread Destroyed] in the "Thread" window for Visual Studio 2010
I tried to debug some issues related to threads with a single application. When I attach to the application, I see a window like this:

What is this thread named "[Thread Destroyed]"? Application code does not write this name.
Which means that Thread has a call stack that is not available. The Engine Engine thread is created inside the application and runs inside the loop until it stops. If a thread is stopped, it exits the loop and it ends its life, so it should be on the list of threads. If he is there because he has not yet left the loop, then again, what does it mean that the call is not available?
Thanks in advance for your help; this does not seem easy.
[Thread Destroyed] means that Destructor has been called and the thread no longer exists.
