Well, I tracked that timeline belongs to SimulatorCore. SimulatorCore
is passed as an input to the class of Simulator in pysim.py.
I tried removing _state, but Simulator object has no attribute timeline.

That's where my skills end. I have no idea how to access the passed
SimulatorCore from Simulator.
