Yep - even with multiple disks all the server process soon end up
trying to process requests for the 'busy' disk.
To make multiple server processes work well, there would have to be
a separate queue for each disk spindle.
But AFAIK the server processes just pull the next request off a single
queue - originally the udp socket.
