Test program 2 (C99)

You mean "can" as in "I think it does" or "it did for me"?

And anyway, it seems to only fix the most proximate cause of the crash. My
biggest worry is that KVM_SET_USER_MEMORY_REGION ioctls with guest_phys_addr
around the 0xfff00000 to 0xffff0000 range seem not to "register"; starting the
VM looks like as if the region wasn't placed there.

I attach test program 2. Running that on my system with 0x44000 as an argument
outputs "halted" (as expected), but 0x45000 and larger multiples of 0x1000 give
"internal error, subcode 1".
