Several of the emails in this thread were missing the In-Reply-To 
header.  Some mail clients (e.g. Thunderbird) will only thread messages 
if they have a chain using that header or one of the closely related 
ones.  This means you end up with split threads when someone doesn't 
reply properly.  Others (e.g. Apple Mail) will use some heuristics to 
try to infer threads.  This means you end up with weird interleaving of 
totally unrelated threads when the heuristic is incorrect.

In general, if you're replying to a mailing list post, please always use 
a reply button in your mail client and if your mail client then does not 
put the correct In-Reply-To header then please file a bug!
