      Revert "v8::ItemParallelJob : Do not launch more Tasks than there are Items to process." · 2407b2bd
      Gabriel Charette authored
      This reverts commit 8a27c7d3.
      
      Reason for revert: 
      
      Having more tasks then work items is intentional in some use cases, i.e. Scavenging where RunInParallel() does parallel processing on a dynamic workload *after* the initial set of work items:
      
          {
            barrier_->Start();
            TimedScope scope(&scavenging_time);
            PageScavengingItem* item = nullptr;
            while ((item = GetItem<PageScavengingItem>()) != nullptr) {
              item->Process(scavenger_);
              item->MarkFinished();
            }
            do {
              scavenger_->Process(barrier_);
            } while (!barrier_->Wait());
            scavenger_->Process();
          }
