I understand it perfectly.  I take the same position with kvm.  I'm 
providing more data in the hope that you'll change you mind, not trying 
to flood you with email so you'll give up.

We can always create our eventfd-lookalike for kvm, but I'd rather not 
do that (other options include a userspace proxy through existing 
interfaces, it might even be better than changing eventfd if we decide 
performance for level-triggered interrupts is not critical).
