/dev/null and KSE panic 100% reproducible

[Robert Watson]

Just for my benefit, could you check and see if you still get the
reproduceable KSE panic without the MAC stuff compiled into the kernel? 
If not, it could have gone away because the bug is in the MAC code,
because the bug was encouraged by the MAC code, or because it was a
ordering/timing thing and it was a fluke that it occured consistently.
Regardless, if you can reproduce it without MAC, it will also mean it's
likely not my fault :-).

I'll try installing the linux emulator base stuff on some test machines
today -- just installing it is enough to trigger it?
