A new command is being added while another can be executed. The scheme works by adding two WAIT commands after each sent batch of commands. When the next batch is prepared it is added after the WAIT commands then the WAITs are replaced with single JUMP -command to the new batch. The the DBRI is forced to reread the last WAIT +command to the new batch. Then the DBRI is forced to reread the last WAIT command (replaced by the JUMP by then).
