sorry, but i dont follow.  we call __pthread_mutex_init() on the dd_lock 
member of the dirent structure which should initialize the mutex just fine.  
you cant assume that zeroing the structure is the same as initializing the 
mutex.  that is why we have these initializer functions in the first place.  
are you suggesting that the __pthread_mutex_init() function is not doing its 
job ?
