facebook load balancers had this problem for a while, and with their
idiotic 60 second TTL it was a disaster.  but they fixed it after a
few months.  

really needs to be fixed on the broken end, IMHO.  but if you are too
obsinate, arrogant firefox assholes will start shipping its own
resolver and sending UDP itself instead of getaddrinfo().
