Steven Fackler 08f6380a9f Rewrite Condvar::wait_timeout and make it public ... **The implementation is a direct adaptation of libcxx's condition_variable implementation.** pthread_cond_timedwait uses the non-monotonic system clock. It's possible to change the clock to a monotonic via pthread_cond_attr, but this is incompatible with static initialization. To deal with this, we calculate the timeout using the system clock, and maintain a separate record of the start and end times with a monotonic clock to be used for calculation of the return value.		2015-01-16 09:17:37 -08:00
