Yes. This is true. But with a caching resolver being used for most 
interactive clients (web surfers), this doesn't cause any problem, other 
than the initial caching.

OK I guess the question is this: How many milliseconds now on average 
does it take for my local dns server to obtain an address which is 
uncached using recursion up to the authoritative end using UDP
And I guess the second question is: How many milliseconds on average 
would it take for my local dns server to obtain an address which is 
uncached using recursion up to the authoritative end using TCP.

Once it is cached on my local caching server, its a non-issue if I am 
using some sort of persistent connection to my (non-authoritative) dns 
caching server.
