The name ResidentSetSize isn't a perfect fit for the values extracted from MacOS and Windows, but I think it is better to name this after something that many people are familiar with instead of trying to find a generic name that fits all platforms. Do you agree with that, or should we change it to something else?

I agree. What's important is that end-users understand the concept. If there are differences between OS:es (worth mentioning) they can be stated in the description of the event, i.e. "On MacOs X is included, but not Y"
