Can we avoid unrelated format changes for this PR?
Lets focus on the main changes

Done.
Although I do prefer to fix bad formatting where I make changes anyway. Could be more easily compared in the VSCode view :-)

This shouldn't work!
Make the shared - good.
Make the weak - good.
Destroy the shared - because nobody's holding it!
Now in the callback, weak.lock() has no strong pointer alive, it will return null...
@OhadMeir please review

You are right.
I think we missed that
bool _is_alive;
should be
std::shared_ptr<bool> _is_alive;
and add the _alive(make_shared<bool>(true)).. in the Ctor or something like that.
