ThreadedWrapperHandler does not pass all LogRecord contents to thread

[aragilar]

This may be sign more a bigger underlying issue, but it appears ThreadedWrapperHandler drops exc_info somewhere along the flow such that it does not include it in the output (but the unwrapped handler does). I'll try to create a minimal PoC to help chase this down when I have a bit more time.

Is this a case of exc_info=True? I think that means sys.exc_info() will be called on the receiving thread which is too late
