That isn't helpful. But if you feel like that I suggest you run with your
memory management protection disabled, it's really on there to deal with
crap code and its giving the wrong incentives. Come to think of it
you might want to remove your seatbelts and any safety catches or airbags
- it only encourages carelessness.

The reality is you need a sane, generic, race free way to express your
requirements (eg for hard RT) and ditto for constraining the expression
(for 'crapplications')

Arguing that you don't need to do this isn't useful. Android has
demonstrated a need to do this. RT has a need to do some of this.
Virtualisation wants elements of this etc.

The question is how you do it right.
