so when someone is using gmail on a macOS system, how are they using cgroups in any way? how is "the whole google" built on this? perhaps you means "google's web-facing servers using cgroups extensively" ?
That is a somewhat weird and dare I say pointless take. Thousands of machines are involved in serving every request from a web browser to gmail. Of those, only the web browser might not be in linux cgroups.
