That's the idea, both because you're cutting out the overhead of simulating a
network (and all the protocol processing) and because it exposes more
knowledge about the underlying system - which could enable more optimisations
(such as sharing the same cached filesystem data between multiple domains).

But the code in there is very buggy and nasty ;-) It might hurt your brain!
There are loads of flaws in it.

It's definitely not ready for deployment. It's incomplete and buggy, although
it's still under development so maybe one day it'll be usable!

No problem!
