This is a Linux specific way of pinning a process to a numa zone, and it
may not even be for all flavors of Linux. We need a good way to turning this
off for other systems, and ideally providing a way for them to override this if
needed so things will work for them in the future. It is okay to output a
large warning if you are on an unsupported system.
