A bigger issue is distinguishing the round trip time of your
ping response versus the latency of when your process gets scheduled.

Another issue to be aware of is that, on the wider Internet, pings can be very unreliable (because misguided network admins filter them out *sigh*). So, if you're running in a relatively constrained environment, go with the ping approach. OTOH, if you want to work in all network environments, you'll need a backup plan.
