Another round of speculative-execution vulnerabilities

> All of these vulnerabilities exist because we have shared state in the hardware between two threads with different access rights; how far away is a world where we can afford to let some CPU cores be near-idle so that threads with different access rights don't share state?

Aren't we there already? If all your cores run at full power your chip will fry in seconds?

Just allocate one job per core and let the chip allocate power to whatever job is ready to run.
