Anti-nasty system, maybe. The prefetching thing can't possibly be implemented by the DNS cache daemon because it doesn't know what the user is currently typing.
I was speaking about the fact that Chrome also re-fetch some of the (most used) DNS entries in the background when they are about to expire (like they do for the DNS "8.8.8.8" servers).
I agree that prefetching however can't be done by a DNS cache program.
