Don't we want to use TaskRunner::WaitForNextCompletedTask() here? I don't see any benefit for using TaskRunner::WaitForNextCompletedTask() here because we can't really do anything when only a few task is completed and using TaskRunner ads an extra layer of indirection (to implement WaitForNextCompletedTask) what have a very minor performance hit. One possible improvement we can do is to do the merging of the indexes on the main thread while we are waiting for the parsing tasks to complete, but I am not sure if it will have any performance benefit as it would mean that we do it on a single thread instead of 9 threads we are doing it now (with TaskPool::RunTasks).
