This just creates a race condition:


Is this functioning code? It looks like it *should* be but it isn't.
The answer to the `joinable` question is out-of-date the moment after
you call the function. If the thread function exits *after* the
joining thread asks if it is joinable, then the call to `join` will

So even if this were solving a problem, it's creating a new problem in turn.
