> I still object to changing the semantics of events. I don't know what you mean by common definition of event. I prefer tom stand by the CSP definition of events, which underpins process algebras (see eg http://en.wikipedia.org/wiki/Communicating_sequential_processes)

> Events
> Events represent communications or interactions. They are assumed to be indivisible and instantaneous. They may be atomic names (e.g. on, off), compound names (e.g. valve.open, valve.close), or input/output events (e.g. mouse?xy, screen!bitmap).

> We have more modestly encoded a small set of events, and these are certainly fundamentally distinct from processes.
