The fix doesn't work without them because the is_external handling in
the main loop is incomplete (i.e. even after aio_disable_external() it
would still process the AioHandlers sometimes)

I think it makes more sense to merge them in a single batch. I can
either take v3 through my tree as soon as Fam posts it or Peter can
apply the series directly.
