Understand, _SuspendSimulation and StopSimulation
are the internal exceptions (state) for the simulator.

When you run the simulator for a specific period
of time:

     sim = Simulation(tb())
     sim.run(100)

The simulator suspends so that it can resume:

     sim.run(100)

In my example I did not define a number of simulation
steps to run (the argument to run).  When no duration
is specified the simulation runs until there are no
more events or StopSimulation is raised.

Restarting the simulator in the second condition works
fine but restarting in the first has an issue.

The raising of _SuspendSimulation is not the bug, the
bug is when a new simulation instance is created after
a suspend.
