Yes, but with composed operations (such as asio::async_read) you may
also get bad_descriptor if you just happened to close the socket in
between two individual async_read_some operations. It may be better to
write something like:

  if (sock.is_open() && error) ...

I.e. if sock.is_open() returns false then it's because you have
explicitly closed the socket.
