Could it be that you have your NS service from MyDomain who has many many customers on their servers. This delay should only happen when your nearest DNS don't have the domain cached. You have 900 seconds TTL on www.peterbe.com, which means that local DNS servers needs to ask mydomain again quite often...
BTW I tried it on one of my static sites and got a lot of bogus results. But the DNS resolving time for my .se address hosted on my own TinyDNS was a third of yours with the same UK testserver as you used (I think). Maybe is .SE faster than .COM also.
BTW2 We meet @ Euro DjangoCon where we had a short lunch together one day at the conferance.
