Do you have any sources for this? My googling skills are failing me. I'm surprised early x86 (which I assume you're including) were aware of security issues with accurate clocks; I certainly wasn't until this millennium :D I would rather guess observed clock jitter would be explained by interrupts or some such. Not saying you're wrong, I'd just like to learn more.
