 Hi, sometimes throw exception and function CUCListener::OnAccept not
 called when connected

 socket_ops.ipp

 {{{
 socket_type socket(int af, int type, int protocol,
     boost::system::error_code& ec)
 {
   clear_last_error();

   socket_type s = error_wrapper(::WSASocketW(af, type, protocol, 0, 0,
         WSA_FLAG_OVERLAPPED), ec); // Exception Throw
   if (s == invalid_socket)
     return s;
 ...
 }
