- * Implement gras_datadesc_cpy to speedup things in the simulator
- (and allow to have several "actors" within the same unix process).
- For now, we mimick closely the RL even in SG. It was easier to do
- since the datadesc layer is unchanged, but it is not needed and
- hinders performance.
- gras_datadesc_cpy needs to provide the size of the corresponding messages, so
- that we can report it into the simulator.
