I've only been using nscd attempting to cache hosts.  Using it
again, I'm not having the problems I had before, but
the trace does not show any activity either.

The issue before was that getting rss messages would lock
up the browser or make it segfault.  There was a domain that
would not resolve at that time because the server for the feed
was down for several days.  When I stopped running nscd there
were no more segfaults or lockups.
