It could be cool if there was a Kernel simulator with memory protection...

Protection of what? Read/write memory in the kernel map is freely writable by any code within the kernel; this is what being a "monolithic" kernel is all about.

Optional redzones, as well as use-after-free, use of uninitialized data, etc, would be welcome. Solaris does this with boot-time tunables (kmem_flags), and FreeBSD and linux do much of this with compile time options. A redzone may have caught Stephane's corruption as it happened..
