Every time I tried to push the page flip idea or offloading or any of
that crap, Andy Bechtolsheim would tell "the CPUs will get faster faster
than you can make that work".  He was right.

I really don't see why receive is so much of a big deal
compared to send, and we do a send side version of this
stuff already with zero problems.

Hey, maybe it isn't, but could you please quantify the cost of the VM 
operations?  How hard is that?
