Indeed you did. I've moved the entire queue tree to a partition on the
server which was *not* 97% full, sorted the Rackshack-shutting-down-its-
nameservers problem (thanks, Dean, for the stopgap, assuming it was you)
and increased the output concurrency of the mail server from 20 to 100
simultaneous connections.

Last I checked, thelist was roundtripping in < 2 mins again, and CSS-d 
was chugging its way through a backlog plus its very own special "lots 
of duff subscriber addresses" issues.

CCing this to Elfur and Eric Meyer for background.
