Using qemu is an interesting idea, but would be difficult to generalize.

I actually do agree with you that a test like this may not be 
appropriate for
LTP since it's so separate and alien to the rest of the LTP suite.

I need to confirm internally before I make a decision here, but is there
a better place to put a test like this?
