I think we can debate this one forever... but again, Ild suggest comapring
it to Solaris or Amiga's Intuition. All events are ultimately IO related,
thats is the defintion of event driven code-- that it reactes to IO ratehr
then polling IO when it is ready to and then waiting o na response.
I think to make your poitn vaild you need to explain what the differnece
between an "internal event" and a message pass is, in your model. I see no
practical difference. In my model and in the term event driven as I
understand it to be commonly used, the only difference is that the call
coems from the OS... which is to say it happens inresponse to IO (or the
clock, which is aslo a form of IO really.)
