Comment (by asn):

 Actually, do we even want this feature? Isn't the exponential backoff what
 we want to do here, and we are already doing it? So what's the point of
 doing both exponential backoff and completely blocking fetches after 8
 tries?

 Furthermore, this seems to also apply to dirservers, and we don't want
 dirservers to abandon md downloads since then they stay incomplete.

 Do we have a reason for keeping this feature? I'm trigger happy here.
