Sure, but at the time Jeff Bonwick chose it, it had no meaning in computer science or operating system design. Whatever name is chosen, we'll get used to it. I don't even care what name it is. I want "short" because it ends up used everywhere. I don't want to be typing lock_hippopotamus(hippopotamus); and I want greppable so it's not confused with something somebody else has already used as an identifier.
