You can easily achieve the same semantic results. In the binary protocol, you can get with CAS and then delete with CAS and confirm both: a) You deleted the thing you got. b) You were the only client to have done so. If the deletion succeeds, you were the only one to observe this value and nobody else can. If the deletion fails, you ignore the value you retrieved. -- dustin
