A good question. I'll decide whether the parent or child runs next, and add the 'answer' to the Clarifications.

Yes, the parent only waits for the child if the parent calls wait.

> For CPU Measurement is the total time the CPU spends executing the process divided by the total time of emulation, the right way of going about it

Yes, the ratio of CPU-time-consumed-by-all-processes and the difference-bewteen-booting-and-completing-all-processes. As time is (nearly) always consumed when switching states, and when having nothing to do except wait for something to happen, the ratio will (nearly) always be less than 100%.
