You are right about that but honestly it is irresistible for me to go for the obvious punchline :) For those that don't know, I am referring to "callbacks." I want to straight adapt it into coroutines as much as possible.
Conditional variables are an anti-pattern in asynchronous code, because the wait state ties up the calling thread. 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).
