I finally had the problem reproduce.  It only really appears to happen
to me when changing from wireless to wired (when I get
back home to my desk for instance).

In that situation, icecat would fail to resolve any hostnames.  However
when I do "# herd stop nscd" like you suggested icecat immediately
starts working again.  So perhaps nscd is being a bit sticky to which
interface it should be using?
