Long running queries on the secondary with WT

      We have disabled yielding with WT, because it is not necessary due to the use of snapshots.

      On secondaries though, because of the way the Parallel Batch Writer lock is implemented, it is possible that a long running query would prevent the log applier threads from starting until it is completed and thus cause backlog.

      This ticket is to verify this behaviour and if it turns out to be true to figure out a solution.
