Loops are certainly an important concern, but traditionally they were
dealt with by the gateway injecting a gateway-specific header such as 
"X-Loop: XXXX".

My newsreader (Gnus v5.10.6) uses the "References:" header to walk up
the thread.  It asks the nntp server (in my case news.sonic.net) to
hand it the articles with the mentioned Message-Id's.  Are you saying
that mailman expects it to do something differently?  If gnus is
screwing up, I'm quite willing to fix it and submit some diffs, but I
really can't see any problems other than the message id's mentioned in
the References header not really existing on the nntp server.
