I should mention another possible trigger for dccifd being slow
arbitrarily slow.  If you use host names in /var/dcc/whiteclnt
and if /var/dcc/whiteclnt.dccw is invalid, then dccifd cannot
use a separate thread to resolve those host names.  The whole
thing must stop until your local DNS resolver library gives answers.
