This is the right approach, IMHO. Let me run local apps like video rendering and transcoding using all cores, but let me mark anything that has Internet access as only executing on a dedicated core. Apple's new hardware approach might work well for this: on the A12X chip used by the new iPad Pro, they have 4 high performance cores and 4 low power cores. Let Chrome have a couple low power cores, and that solves a few problems: 1. I get security isolation between Chrome and the rest of my apps. 2. I no longer care very much when poorly written javascript wants to consume 100% of CPU because it's only running on a low power core. 3. My battery life is also better because Chrome can't consume a high power core.
