Don't think that its disk access, but I could be wrong.  Box has 512MB of 
RAM, and with the volume of traffic we've got coming in to this machine 
the Mailman database should be stuck in cache perpetually.  I could be 
totally wrong here, but I'm inclined to believe that its not disk IO thats 
holding this one up.
