* - For communications, this function is called from SIMIX_comm_finish().
* This function itself don't mess with the order since simcalls are handled in FIFO order.
* The function is called:
* - before the comm starts (invalid parameters, or resource already dead or whatever).
* The order then trivial holds since maestro didn't interrupt its handling of the simcall yet
