Can I specify the resolver timeout?

We have two internal DNS servers in a FreeBSD web cluster. If the first DNS
server fails then after a timeout period the client's resolver will try the
second DNS server. This works fine, but is a bit slow. It looks like the
timeout takes 10 to 15 seconds on FreeBSD 4.9-STABLE. Is there a way to
override this timeout value? I know it is possible on other UNIX systems,
such as AIX.

Basically, we want to get a response within 3 seconds or the resolver should
try the second DNS server.
