Internet connection in android emulator

I have no idea, what am i doing wrong

I want to turn off internet connection in emulator (Android 2.2)

I'm pressing F8 -> no effect, i still have internet connection

I turn airplane mode -> no effect, i still have internet connection.

I go to settings for check, airplane mode is on, wifi is off, but there is internet connection on device.

What is wrong?!

Please, don't suggest to turn off internet on my computer. I know, it's the solution for sure, but not the best one

P.s.

It is probably the bug http://code.google.com/p/android/issues/detail?id=3838

I tried to disable connection in emulator for android 1.5 and it works fine there.
