"options single-request" in /etc/resolv.conf works, but it has two drawbacks:
1) The first time you want to access a website, it will be slow.
2) when the process terminates, i.e. when you close the application or when it ends by itself (web browser, apt-get, etc.), you lose all your "fast DNS resolving" stuff. When you reopen the browser, it will be slow again. Take apt-get: you run it for updating or installing some packages, and it will close itself at the end of the operation, and all is lost. Next time you run apt-get, it has to resolve everything again with the slow method...
