Why can't you just say "unlock semantics"? It's not as bad as all that; people do talk about acquiring and releasing locks, and presumably you don't have any trouble understanding those terms. In fact this usage is quite common -- and I believe it's where the names "acquire semantics" and "release semantics" came from originally. Alan Stern
