As Terry's recent experience shows, Mailing-lists run on threads and rely on reply-to headers to
stitch emails into threads.

If you* hit REPLY and change the subject, it does not create a new thread.

Mailing-lists and most email clients are pretty dumb.

The Forum used to be a bit smarter about it, but the Forum is dead, long live the Forum.

So please create a new email for new topics, it is not that hard to type 'o','p','e' etc until the
right email address gets auto filled.

*Bob with 'path_sweep problem' in this case, but he is not alone.

There's an unfortunate gray area, where a discussion has started with
topic A, and has drifted off onto topic B.  At some point, my personal
tendency is to reply and change the subject line to B, so that it's
still connected to the previous messages (which were discussing B,
just under the wrong subject), but now shows that this subtree is about B.

While (obviously) I think that practice makes sense, it does mean that
an "ignore thread" operation is likely to suppress both the original A
and the drifted-to B.
