Note3: The simulation will run for one poke period before the handbrake starts.
So expect to see simulations to last approx. 1 poke period less than specified

Note4: If the host machine is too slow to keep up with the requested ratio,
the handbrake will not stall the simulation. In that case a warning will be
printed at verbosity level 4 indicating how far behind real time the
simulation is lagging.
