Detecting a crash can likely be done within one timeslice of the simulation (processor A calculates the new state of the right hemisphere, waits for processor B, waits, waits, times out and tries to start up a new left hemisphere simulation based on stored data), so the right hemisphere will just experience things up to the end of the timeslice, which likely is extremely short. If it uses delayed evaluation and other tricks, things can get stranger.
