I know, it's as designed, as the comment says. But you could of course argue for that it should be polled at first poll attempt. In practice it would not be that much of a difference when you have a thread polling forever. 

Also, it could be argued what the best frequency is. 10 is more or less taken out of the blue :) It should be a tradeoff between "not stealing the error messages too often" and "be able to process error messages fast enough".
