Because you're posting using the Google Groups web interface, right?  
Google Groups is just plain busted and double-posts everything (at least 
to this group).  Not your fault, but something to be aware of.  You'd do 
better to subscribe to the real email list, or use a traditional NNTP 
newsreader.

Google's motto may be "don't be evil", but they get to define what evil 
is.  Apparently working and playing well with mailing list technology 
which has worked just fine for literally decades isn't part of the 
definition.
