completly different topic

if i install a local resolver and start it it caches - so what - the 
same for nscd which is not default, so you can't blame glibc because 
caching of an additional package

tell me one reason why *any* application has to cache DNS results at 
it's own - it don't matter at all if the machine has a local 
resolver/cache or not, it's not the business of any user application

and just because you have a local resolver firefox won't stop it's behavior
