+* Add new POSIX-proposed pthread_cond_clockwait, pthread_mutex_clocklock,
+ pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock and sem_clockwait
+ functions. These behave similarly to their "timed" equivalents, but also
+ accept a clockid_t parameter to determine which clock their timeout should
