lets check whether it's even possible ... Then we could ask Intel to
clarify their position on this. I can see no real reason why a vmclear
should really make it impossible to re-use the already loaded context
data /on the same CPU/. And that is the important case. When we migrate
to another CPU we have to do a VMLAUNCH anyway, upon the first execution
of that context.
