The djbdns client library's approach could be useful.
<URL:http://cr.yp.to/djbdns/resolve.html>:
* Most long-running programs don't notice changes in
/etc/resolv.conf; they read /etc/resolv.conf when they start, and
they don't reread it until they are restarted. In contrast, the
djbdns procedure checks for changes every 10 minutes or 10000
uses.
