> The MQTT Retain implementation uses special address to handling retained messages.  Any retained message received will be forwarded to the appropriate address and a copy sent to the special retain address.
> Since we are not uses pooled buffers, the buffer allocation for copies of retained messages can be high.  We should try to use a message reference instead of copy.
