Has anyone discussed how this can increase the precision of fingerprinting?  It seems to reveal more information or more precise information about what else is going on on a user’s system.

> Description:
> We propose a new API that conveys the utilization of CPU resources on the user's device. This API targets applications that can trade off CPU resources for an improved user experience. For example, many applications can render video effects with varying degrees of sophistication. These applications aim to provide the best user experience, while avoiding driving the user's device in a high CPU utilization regime.
> High CPU utilization is undesirable because it strongly degrades the user experience. Many smartphones, tablets and laptops become uncomfortably hot to the touch. The fans in laptops and desktops become so loud that they disrupt conversations or the users’ ability to focus. In many cases, a device under high CPU utilization appears to be unresponsive, as the operating system may fail to schedule the threads advancing the task that the user is waiting for.
