But this is still confusing if you use the word "asynchronous" to describe the sender or the message that is sent. If I'm unaware of your state as a receiver and I send you a message, am I sending synchronously or asynchronously? This usage seems wrong, and I think the definition adopted should rule it out. That means "synchronous" as applied to event sets means constraints on the timing of the events. And it means "synchronous" as applied to an application behavior means an intent or an expectation to accomplish something within a deadline, generally. I realize these interpretations don't directly say what you want them to. What I'm wondering is whether they are correct enough to be applied to specific cases through example. (I'm really trying to find some commond ground among the theorists and pragmatists here.) Walden
