I think his point was that a person who *does* understand parallelism and  
threading couldn't get it right.  Not being an expert in the *language*  
does not make you a novice at threading.

Of course someone who does not understand threading/parallelism is bound  
to have troubles no matter what the language until he/she gains more  
experience.  You almost have to experience a deadlock-after-2-weeks  
problem to really get how important threading issues are (I did).
