To give it a positive turn, for the moment I'd prefer to roll this
back and have the two types pthread_mutex_t and pthread_cond_t violate
the namespace rules of libc for the moment. This is not perfect, but
also not a serious drawback.
This would have the advantage of being conservative on the pthread
side and not to delay the schedule.
