Split enumeration is stopped when there are enough tasks to be scheduled in the task queue. However split enumeration should continue for stages that have at least one "open" task (task that doesn't have the complete set of splits assigned). Otherwise there is a chance that "open" tasks may never finish and split enumeration process may never get resumed.
