-   * For list commands:
-   *  - deallocate request
-   *  - deallocate response _payload_
+   * The message is originally received by a listener, and will be freed in
+   * different parts of the code.
    *
-   * For other commands, generating a ACK/NACK packet:
-   *  - deallocate request
-   *  - deallocate response, as the ACK/Nack is allocated
+   * For the special case of commands, a iovec is created, eg in
+   * udpListener::_readCommand, which has to be freed (it is commented in the
+   * listener). On the contrary, the original message is freed.
+   *
+   * From this function, commands are dispatched to different processing
+   * functions, which have two general behaviours:
+   *
+   * - LIST commands:
+   *   . a payload for the response is allocated
+   *   . a iovec for the response is allocated with header = request header,
+   *   payload = newly allocated payload
+   *
+   * - Other commands:
+   *   . a ack/nack packet is generated thanks to utils/utils.cc
+   *   . this allocates a iovec which reuses the header of the request just
+   *   updating the messageType field inside.
