In the analogy to the naked short, the option is "called" when the known deficiency causes catastrophic consequences. Example: The file system is so large it takes 60 days for the backup to finish, and thus the "call" would be a multiple drive failure requiring a full restore. Example: NFSv3 with "system" security, i.e., whatever the client says it's uid and gids are, we accept that, and thus the "call" would be a malicious client declaring arbitrary unauthenticated uid/gids. See, e.g., possible publicity stunt for the movie "hackers". These are naked shorts because there are no plans to fix them.
