I don't know how it's supposed to work but this code looks incorrect (or at least it's very bad design from C++ point of view). Adding ref-counting to the context is not really an option (because C++ objects are not managing memory used to store class structure). Maybe ThreadScheduler should be responsible for creating/managing contexts, but it looks like we're missing something.
I would like to see some tests (even if we can't add it to wine for some reason). I didn't test it myself but I hope to give you some hints after playing with them.

I opted to not do this for now because running chores do not block thread exits, and there is refcounting so this case should not be hit anyway. If I should still add this please let me know.
It's not needed if the problem is solved in different way. The problem is that ref-counting solution also looks wrong.
because C++ objects are not managing memory used to store class structure
We are though. We are the ones calling operator_new.
I don't see why we can't reference-count our allocated instances.
I also don't see how moving the Context creation to TaskScheduler would work and how it would help, could you elaborate please? And I'm not sure how I can test who manages the Contexts.
