I think the miscommunication is around "shuts everything down". Some of us are reading that as an emergency power-off event far beyond normal thermal throttling, which is just a reduction in clock speeds within the typical variable clock range of the power management system. I don't know if it still holds, but some older systems also had a third category of throttling in between the normal speed range and an emergency power off. They would stutter badly as if they were applying some duty cycle and alternating between a suspended state and a slowly clocked state. This would show up as really frustrating IO buffering and UI latency, similar to how a machine might behave if it were stuck in a virtual-memory swapping storm and processes would freeze/unfreeze sporadically.
