Using /dev/kUmem is a really good way to crash the system.  If you try
to touch a non-existent address, the system crashes (at least our 4.1
system did).  Not too healthy.  Besides, you can write all over ANYTHING
with it.  Not too good for system security.  I mean, suppose you
accidently write on the disk drive registers?
