This includes ClockMonotonicNanoseconds() and SleepNanoseconds(). SleepNanoseconds() is like base::PlatformThread::Sleep(), but PlatformThread is not in mini_chromium and I’m not keen on adding it because I’m not sold on the interface. I’m not convinced Sleep() belongs there, and I don’t want to have to bring all of base::Time* along for the ride.
