I wouldn't expect another domain's workload to affect the test domain's time
synchronisation except so far as the workload affects the domain's CPU
demand over time. I imagine you could therefore simulate that CPU demand
process inside the scheduler. How hard that is presumably depends how
accurate you want the simulation to be.
