So this is interesting. So far today with that change, I've not been able
to reproduce the "NMI watchdog kicks in, and then locks up the box", but I keep
hitting lockups which cause the kernel to taint, and then the fuzzer
would usually quit. I hacked something up so it would ignore that, and keep
going, and it spews a lot of traces, but it does actually seem to be staying up.

Example of the spew-o-rama below.
