It is, but there is also precedent for not using it for graceful
shutdown. Apache, for example, will do what we do today on SIGTERM and
you use SIGWINCH to make it shut down gracefully (which would be the
equivalent of us flushing the compression buffers, I'd say).
I'm not saying we shouldn't change -- I fully approve of making the
change. But the world is full of fairly prominent examples of the
other way as well.
I'm leaning towards considering it a feature-change and thus not
something to backpatch (I'd be OK sneaking it into 15 though, as that
one is not released yet and it feels like a perfectly *safe* change).
Not enough to insist on it, but it seems "slightly more correct".
