Isn't this similar to a file? If a file gets closed() before the file
object is destroyed, the file object is in a "closed" state until the
destructor runs.

If the function invoked by the thread constructor exits or the thread of
execution dies in some other way, then the thread object is logically in a
"closed" state.
