We can have a flag on the async gen object to make sure that we run the finalizer only once. The finalizer will likely schedule async_gen.aclose() coroutine which will ensure a strong ref to the gen until it is closed. This can actually work.. ;) Yury _______________________________________________ Async-sig mailing list Async-sig@python.org https://mail.python.org/mailman/listinfo/async-sig Code of Conduct: https://www.python.org/psf/codeofconduct/
