I disagree.  The distinct thread IDs allow one to distill the output contributed by different threads.  One can filter the output to see only that for a particular thread, for example.  The output logged will indicate the thread, if the threads are created for different tasks.  If the threads are simply divvying up parallelizable work, then the separate IDs are still useful to understand how much work was done by each thread and, perhaps, how the work was divided.
