Comment (by arma):

 I'm not so good with this code, but I can confirm that the patch seems to
 have the behavior that teor describes. (The code used to launch two
 consensus fetches in parallel, one to an authority and one to a guard or
 fallback. Now it launches only one, not to an authority, and 1 second
 later if needed it launches another, also not to an authority. I didn't
 try triggering stuff after that, but hey, what could go wrong. :)

 Agreed it is smart to put this patch into 0.3.1. In fact, we might not
 need/want to backport it before that -- since it's the sort of thing where
 it will be a long time until we realize our mistake, if there is one.
