I think there's little reason now.  One thing we need to do is make it 
possible to call the injection code twice without entering the guest.  I 
think right now it assumes nothing has been injected.

We need either to cancel a previous injection (a variant of 
vmx_complete_interrupts()), or avoid reinjecting  if we already did.
