"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. Is that really true?
