The problem there is that in some systems (notably CNews) a POST command
does not immediately make that article available to be retrieved by an
ARTICLE command (it just gets queued, and the queue is processed
periodically by a cron job). There is another place in the draft (can't
remember exactly where) where we have had to make allowance for that sort
of behaviour.
