It's indeed not a very good choice, but the new name is even worse.
Just call them non-broken locks? :)  Or not give them a name an just
append a 2 to the fcntls? :)

I don't think so.  They also should have a name very similar because
they have the same semantics with a major bug fixed.  In fact I can't
think of anyone who would actually want the old behavior.
