What I mean is that we get a warning earlier, when the socket is
created in setup_stream(). So the warning here only adds additional
information if the platform pretends to support SO_TIMESTAMP
but does not in fact do so, which I think is not very likely. But I am
also OK with leaving it in if you prefer.
