Are you saying that Windows (Vista in this case) would allow two
to confuse the termination? The state of any of the threads should not
matter, they are to be terminated anyway. In this specific program,
worker thread does not do any write-type operations that make
any permanent changes so its state during termination does not
make any difference.

Of course the state of the threads matters, because the shutdown doesn't
happen immediately. I talked about that in the page I linked to,
specifically, in Q2:

You said earlier:

The program has one worker thread (in addition to the main thread).
Most of the time
it hangs on WaitForSingleObject()

If the main thread tries to lock the same object during its termination,
you have deadlock. More generally, if the main thread tries to lock an
object that can only be unlocked by the blocked thread, you have deadlock.
If the worker thread tries to access something on its way to WFSO that the
main thread has destroyed, you have undefined behavior. And so on and so
