Pickles the record's attribute dictionary in binary format with a length
prefix, and returns it ready for transmission across the socket.
+ Note that pickles aren't completely secure. If you are concerned about
+ security, you may want to override this method to implement a more secure
+ mechanism. For example, you can sign pickles using HMAC and then verify
+ them on the receiving end, or alternatively you can disable unpickling of
+ global objects on the receiving end.
