示例1: timeouts
/**
* Verify that idle time is correctly accounted for when decaying our loop
* time.
*
* This works by creating a high loop time (via usleep), expecting a latency
* callback with known value, and then scheduling a timeout for later. This
* later timeout is far enough in the future that the idle time should have
* caused the loop time to decay.
