I briefly looked at this while in vacation, although I did not reply 
hoping the horrible feeling about this code would go away.
It didn't.
I find this to be an ugly and ad-hoc multiplexing of eventfd with added 
functionalities of questionable general use.
I'm pretty sure you can do better on KVM side, to solve the problem w/out 
littering eventfd.
