Anyway... you could create a `boost::asio::experimental::basic_channel` using the signature `(void)` and then `co_await` the channel to suspend the coroutine. Later when you want to wake it up, send a message to the channel from elsewhere. You will need to be thoughtful about the order of how things are destroyed if you want to tear down the socket (or corresponding I/O object).
