Seeing ConnectionPendingException in my code

      def self.open(host, port, options = {})
        # All this ugly code to ensure proper Socket connect timeout
        addr = Socket.getaddrinfo(host, nil)
        sock = new(Socket.const_get(addr[0][0]), Socket::SOCK_STREAM, 0)
        sock.options = { :host => host, :port => port }.merge(options)
        begin
          sock.connect_nonblock(Socket.pack_sockaddr_in(port, addr[0][3]))
        rescue Errno::EINPROGRESS
          resp = IO.select(nil, [sock], nil, options[:timeout])
          begin
            sock.connect_nonblock(Socket.pack_sockaddr_in(port, addr[0][3]))
          rescue Errno::EISCONN
          end
        end
        sock
      end
