22	* The VMM component is two things at the moment, it's a component doing a few
23	* management and routing tasks, and it's the whole virtual machine monitor
24	* thing. For hysterical reasons, it is not doing all the management that one
25	* would expect, this is instead done by @ref pg_vm. We'll address this
26	* misdesign eventually.
