I'm ambivalent, tbh, but I think it's better to pick one. I thought
we'd picked 'evacuate' based on the TODOs from Matt R:

http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/manager.py#n2985
http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/manager.py#n3093

Incidentally, this isn't at all core to what I'm working on, but I'm
about to start poking it and thought I'd tidy up as I go (as is my
wont). If there's discussion to be had I don't mind dropping this and
moving on.
