+	  the amount of memory used by kernel objects in the system. Those are
+	  fundamentally different from the entities handled by the standard
+	  Memory Controller, which are page-based, and can be swapped. Users of
+	  the kmem extension can use it to guarantee that no group of processes
+	  will ever exhaust kernel resources alone.
