Its the "References:" header that controls threading in mail clients 
that support it.   I'm using thunderbird, and afaik, it won't revert to 
Subject based pseudo threading in the absence of References.   Subject 
line changes don't break the thread, which is why using 'reply' and 
changing the subject to start a new thread makes a mess wherre the new 
thread is buried in the original that it was in reply to....
