Well, I won't call it an audit, so anyone should correct me if I'm 
wrong:
- simple threading is based solely on a list of references provided by 
the libmutt code, which builds it from the References: and In-reply-to: 
fields;
- JWZ threading also uses the Subject: field, but only as a fallback 
for a message that doesn't yield the references list;
- Balsa handles threading in its own code, so nothing assures that it 
will yield the same threads as mutt.

The next time you see a message that's incorrectly threaded, could you 
check its headers?
