That's not what I meant. I meant, are all situations when I should die 
heralded by a Close call, or are there other asynchronous abort signals 
that I should be watching?

That's not what I meant either. I meant, suppose I am currently waiting 
inside Read or something like that when the user hits stop. Will I get a 
Close call at that time, or will it only get called after Read returns 
(e.g. because the same thread is responsible for both calls, or there's 
a convention of interlocking module entry points, or...)
