Yes, I've been fuzzing this for a few hours on both my haswell and core2 
test systems and it's doing great, also survived a reboot cycle.

Tested-by: Vince Weaver <vincent.weaver@...ne.edu>

(Although often things like to crash the instant my tested-by e-mails

I also want to say thanks for all the work everyone has done in getting
