[Boost-users] boost::thread and helgrind

I am currently fooling around with boost::thread. After writing a short 
example program (featuring boost::thread and 
boost::interprocess::interprocess_semaphore), I ran helgrind against it 
and got some "Possible data race" errors.

The program does nothing but start two threads and serialize them via 
the semaphore and I am unsure whether
a) I did some error I am not aware of
b) helgrind reports false positives

I would be glad if someone could look at my code (attached) and give me 
a hint.
