I applied the patches and looked with notmuch-emacs for threads
which before would probably show wrong ordering of messages.  The
half a dozen threads were all shown in the correct order with
respect to parents and children, but I found from those not
disclosable RT ticket mails (I mentioned in above referenced
thread):

- Threads where the "Resolved" message was shown first but it's
  References: header contains only a fake Message-Id: (which is
  strange: why does notmuch show this resolved-mail in this
  thread?).  


- one thread where two children of one message were shown with
  correct (meaning: same) indentation but the older one before
  (over) the newer one.


I'll ask if I may disclose this threads if this it would be
helpful for diagnosis.


Thanks for your attention and work regarding my problem report
with notmuch.

Ciao; Gregor
