bored, so I did his job :).

I'm not sure how fatal if would be if the idle queue of NS lookups
hangs, but this fix won't hurt anyway, so I better fix it.

very very sure and gave that a few days of testing.

This is, however, only a half fix as this fixes that it fails when
there's None in waiting_descriptors[2], but actually, there never
should be None, so I have to investigate why there was none.

This patch is, however, correct and needed and the other queues also
have that check. It's just that I also need to fix the reason for
the None in the queue.
