It looks like this touches vcpu initialization, which is pretty core to 
the functionality of a VM as a whole.  Hotplug, on the other hand, while 
an important feature, is much less commonly used.
Given that we're hoping to have an RC5 tomorrow and tag a release next 
week, I think I'd rather these wait until 4.4.1.
