Actually, this is something quite different -- making sure that when the
hypervisor needs to kick the pager into action no events get lost.

On the pvops kernel we need to make sure backends wait for that pager to
get things right. And we halted that for a little while, after your
exchanges with Adin by the end of the year. But we'll be back with the
scheduled programming after the short break ;)
