Agreed.

No, you should either hang until data is available *or* get CCE/length=0
...IF there is still a writer associated with the pipe.
If there is no writer associated with it, I'd expect to get CCG (EOF).

Why?  Because if there is a writer, then you can't say there won't be any
more data, which is what EOF means.


This is like message files, but message files allow the programmer to
choose whether a read on an empty file (that still has a writer) hangs
or comes back with a warning/error.

Agreed.

(English is ambiguous at times...I'm assuming the "should be able to" above
means "it isn't possible now, but it ought to have been"
as opposed to:  "it is possible now")
