Just a brief note.  It's true that we shouldn't use /dev/kmem for this
purpose--that is, I totally agree with Niels in his message.

But I want to point out that /dev/kmem is already accessible because
you can read and write pages of the kernel task with vm_read and
vm_write.  It might even be a good idea someday to have someone write
/dev/kmem and /dev/mem devices.
