Yeah, I got bitten by that too.  Apparently it's deliberate and other
wireless drivers will start to do the same thing soon.

It's totally dumb that the initscritps pause *at all* when the kill switch
is in "kill" mode.  Hopefully one day userspace will get fixed (I assume
the problem is in userspace).
