This particular case is extremely low probability, so I'd like to not
change it if possible. I don't think the extra code to add a noop mode
is justified since we're very unlikely to hit this.
Maybe we could/should change the run/play/record vmethods to return an
error code, but I'd prefer to do that separately if it's done.
