A few things...

* stop using DNS? Problem solved.
* put nagios monitoring on your DNS server?
* put in a second DNS server, and tune your DNS timeout to a very low
value in /etc/resolv.conf (read the man page) before jumping to next
server?

Or you could use the Perl language feature, which is called 'alarm'.
Google around for some code samples.

None of these are actually specific to asterisk, as it turns out. I
don't know of any explicit asterisk method to force a timeout.
