There is a thread-id function in email headers that most people don't
know about because most email client programs ignore it.  It looks like this:

The Bat is a good example of a mail client program that believes in
it.  It allows you to sort messages by thread, but it doesn't pay
attention to changes in the Subject: header.

A long time ago when I was first setting up to use gmail (I use it
primarily as a mail cache and an outgoing mail server I can reach
from anywhere, but never from the web interface), the web interface
specifically said that if you edited the subject line it would start
a new thread.  Apparently they've changed their policy on that.  And
if gmail is paying attention to threads I imagine it will be much
more in the public consciousness than before.
