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.
