Yes, but in practice it's physical memory, not virtual memory, which is
the bottleneck once you start thrashing. If you really want to
guarantee root can do something useful, you need to be able to
dynamically reserve a RSS quota for root as well as reserving the swap
space. Either one on its own is incomplete.
