SIMULATOR HAS NO INTERRUPTS (NON-PREMPTIBLE)

```
Description: The current simulator implementation is has no interrupts and, hence,
is non-preemptible. Also, without simulated interrupt, there can
be no high-fidelity simulated device drivers.

Currently, all timing and serial input is simulated in the IDLE loop:
When nothing is going on in the simulation, the IDLE loop runs and
fakes timer and UART events.
Status: Open
Priority: Low, unless there is a need for developing a higher fidelity simulation
I have been thinking about how to implement simulated interrupts in
the simulation. I think a solution would work like this:
