 BTW, local_thread_info->current_cond is protected already by
 local_thread_info->cond_mutex


 {{{
                 boost::pthread::pthread_mutex_scoped_lock
 internal_lock(local_thread_info->cond_mutex);
 BOOST_VERIFY(!pthread_cond_broadcast(local_thread_info->current_cond));
 }}}

 So, for me this is a false positive.
