Actually on second thoughts that big initial delay on the first tune seems to 
be about 3 seconds.... and the initial value of delay in the frontend_thread 
IS 3*HZ... 

In that case, the first attempt to tune if it needed a zigzag scan would fail 
because the initial delay is so huge. Then the next attempt would work, as 
long as the thread hadn't died too fast. 

Sound familiar anyone?
