[issue47246] Race condition in `threadig.Thread._wait_for_tstate_lock`

[Dieter Maurer]

Dieter Maurer <dieter at handshake.de> added the comment:

The observation was caused by a bug which has been fixed in newer Python versions (3.9+ if I remember correctly). `isAlive` was called on a `_DummyThread` (while `_DummyThread` overides `is_alive` it had forgotten to override `isAlive` as well).
