Hi Per,

The pointer vs. reference thing is just some beautification which my itchy 
fingers couldn't help doing - I agree that it's not germane to the problem at 
hand.

If you look at the comments for the class in question (and also all occurrences 
of the code that use this class), you see that the mutex is assumed to already 
be initialized - it's sufficient to lock the mutex without doing any 
initialization on it. That's why I created and used a new macro called 
__glibcxx_mutex_lock_noinit for this purpose.
