Do you cache the failed addresses? The default timeout/retry
algorithm is such that it will sit on a single address for
a *long* time. If you're not caching failures it can take for
ever to repeat the cycle on each hit. You could also wrap a
SIG{ALRM} around the lookup and abort the lookup after 5 or
10 seconds (versus waiting a minute or more depending on
your exact setup).
