+# A message is what is sent when you invoke a method. Args and stuff are packed up in to a Message
+# and the Message is sent to the receiver.
+
+# Part of the housekeeping (see attributes) makes messages a double linked list (next_message and
+#  caller) , and maybe surprisingly this means that we can create all messages at runtime
+# and link them up and never have to touch that list again.
+# All the args and receiver data changes, but the list of messages stays constant.
