This is behavior that I was used to, having worked on HP-UX for years.

However, with my RH 6.1, I noticed that this did *not* work for the
pre-linked network clients, like 'ping' and 'telnet' ('nslookup' *did*
work however, which is reasonable, since it doesn't use the resolver
libraries).

To make clients use the local nameserver, I had to add a "local"
nameserver line to resolv.conf:
    nameserver 0.0.0.0
or  nameserver 127.0.0.1
