[issue17552] socket.sendfile()

akira added the comment: > I'm confused. Why is "blocksize" necessary at all? My guess, it may be used to implement socket.send()-based fallback. Its meaning could be the same as *length* parameter in shutil.copyfileobj The fallback is useful if os.sendfile doesn't exists or it doesn't accept

[issue21351] refcounts not respected at process exit

Antoine Pitrou added the comment: Looking into it, it's normal for refcounts to be "ignored": those objects belong to reference cycles: tstgc.__dict__ -> p (or c, or c2) -> p.__class__ (i.e. Parent, or Child respectivel)) -> Parent.__dict__ -> Parent.__del__ (or Parent.__init__, or Parent.child

Tim Peters added the comment: I think Antoine is right on all counts. The most surprising bit may be that p, c, and c2 are in reference cycles, but - surprising or not - that's always been true. The reason "it worked" before 3.4 is that CPython happened to break the cycles via the nasty hack
