Re: [Boost-users] [Asio]What's the behavior of socket.async_write()after socket.close() is called?

It seems to me. If you call close you want the socket released. That a zombie socket remains is a design problem. Zombie objects should be avoided.

Why is it more zombie, than a fresh "unopened" socket?

Also, the destructor guarantees to cancel any pending asynchronous operation AFAIK.

As far as I can see, it doesn't. shutdown() does.
