if you specify a timeout >15 seconds the plugin reports "OK" although the 
request times out:

[helmut at BSDHelmut ~]$ sudo /usr/local/libexec/nagios/check_dns -H www.yahoo.com -s -t 16
DNS OK: 15.056 seconds response time. www.yahoo.com returns |time=15.055528s;;;0.000000
[helmut at BSDHelmut ~]$ sudo /usr/local/libexec/nagios/check_dns -H www.yahoo.com -s -t 15
CRITICAL - Plugin timed out while executing system call

[helmut at BSDHelmut ~]$ sudo /usr/local/libexec/nagios/check_dns -V check_dns v (nagios-plugins 1.4.15)
