I agree. I do run KVM in simulators which works quite well, but
SLOF ends up being the slowest part, it's also a black box to me
so it's difficult to go about debugging or changing things.

I can't be of much more help with the code I'm sorry, except to
add my +1 for the feature and agree with Greg that the non-vof
changes seem small.

Thanks,
