      Description

      The only way pendingSpeculations is used:

           // If the task is already known to be speculation-bait, don't do anything   
            if (pendingSpeculations.get(task) != null) {                                
              if (pendingSpeculations.get(task).get()) {                                
                return;                                                                 
              }                                                                         
            }
