query for unknown domain hangs

If I do a dig command against my djbdns name server for a domain that I
don't have configured, the dig command hangs for about 15 seconds.

dig @ns1.mynameserver,com somedomain.com

Could this be used for a DoS attack (use up all connections while the
nameserver sits on the requests) or does UDP not have this issue (sorry for
my ignorance here,  its been years since I dealt with UDP)
