Well, yes and no. My testing was showing that `notifyLeftNestedEventLoop` was not even called in the finally block, so there is that. We may still have a problem at the `InvokeLaterDispatcher`, although not 100% sure since it worked good for me on Windows.
But I will test it more as soon as I have more time, since I want to really check everything, so I do not miss anything here.
