The issue is that the simulator already runs about a hundred times
slower than realtime and it's internal clock is only running at 10,000
samples/sec. (see other post).

yep. =(

The issue there is that, in the current simulator, we'd then need to do
something like implement the opamp as something like a pot between two
rails. Which means we'd have to go iterative to tweak the value to where
we want it which would utterly destroy performance, hence the "ideal"
purely linear model the simulator currently uses.
