Correct me if I am wrong, but I thought Varnish has support for limiting concurrent backend fetches to the same resource.

  Across a cluster of varnishes? I think that limit is per varnish.

    No, definitely not across a cluster (although that would be quite nifty). Even on a single node that would reduce the thundering herd effect substantially.

      Maybe that's a new feature request!
