Ok that also makes me rethink commit
ba4877b9ca51f80b5d30f304a46762f0509e1635 which seems to be a similar fix
this time related to idle mode not updating the counters.

Could we fix that by folding the counters before going to idle mode?

That fix seems to now create 2 separate application interuptions because
the vmstat update is not deferred anymore to occur with other events.
