First of all, they should use *early* loading. I don't know how many
times I need to say that, maybe I should print it on T-shirts.
And then they can reboot. If you're thinking of the
"we-can't-reboot-because-we're-cloud" argument don't even bother to
bring it - I've had it more than enough and no, just because cloud
people don't want to reboot, it doesn't mean we will support some insane
use case.
