+	 * a connection is first opened, it is called with IPC_EVENT_NEW_CONNECTION. The
+	 * receiver must take ownership of the connection object. When a connection is
+	 * closed, IPC_EVENT_CONNECTION_CLOSING is generated. At this point (or after) the
+	 * receiver must delete the object. IPC_EVENT_COMMAND is generated when lines of
+	 * text are read, and in this cases the last argument is not NULL. No closed event
+	 * is generated in the event of manual delete if the connection is still open.
+	 *
+	 * Yeah, this whole callback model sort of sucks. Might rethink and replace with
+	 * some kind of actor model or something if it gets too unweildy. But for now the
+	 * use cases are simple enough that it's not too bad.
