Spurious wake-ups return 0. Time-outs return ETIMEDOUT. Normal wake-ups
return 0 provided they occur before the deadline. If a normal wake-up
occurs after the deadline is reached (due to scheduling latency), the
result can be either 0 or ETIMEDOUT.

Overall, EIMEDOUT implies that the deadline has been reached, whereas 0
implies nothing.
