Protecting against kernel NULL-pointer derefs

Pieter's approach to the problem seems reasonable. If it provides some safety
without breaking any/too many applications, why not adopt it?

I wonder how many of these kinds of issues could also be caught with unit
tests/regression tests. See also: the CanSecWest 2009 FreeBSD bugs by
Christer Oberg and Neil Kettle.
