It is not, as far as I can see. Putting the tasks in a queue that is served 
by a thread pool has the advantage that the pool threads do not need to 
block between tasks. Such a pool thread may be able to execute several tasks 
within its timeslice. I don't see how creating a new thread per task, no 
matter how optimized, can achieve the same. But I may be overlooking 
something. :-)
