Here is a link to a reference implementation and a FAQ for mutexes, locks and condition variables I am currently anticipating proposing for C++ standardization (or subsequent TR).

"However if the external mutex is (or is layout compatible with) a pthread_mutex_t, then there is no need for the internal pthread_mutex_t. When one wants to wait, one simply waits on the external pthread_mutex_t with the internal pthread_cond_t." This smells a little fishy. It seems to imply that pthreads can wait on any old data type that happens to be layout-compatible with pthread_mutex_t.
