I've seen this problem as well.  My solution is to run nnmaster from cron
every 15 minutes.  Fifteen minutes doesn't seem like much of a delay, and
when little new news has arrived it runs very quickly.  Perhaps a new
feature of nnmaster would be for it to fork a child to perform the actual
work.  This way if the child exits for any reason, the original nnmaster
is still running to run the update later.  This kind of strategy is
used by sendmail.
