    I want a circuit that will load a power rail if the voltage goes above
    50, and it should current limit.

    This looks OK. I'll use some cheap dual opamp in real iife.

    What's weird is that with some parts values, the sim gets so slow it
    basically stops. Gear integration fixes that.

    I could add one resistor to force the fet gate voltage to truly zero quiescently.
