Well, what can happen with todays implementation on the sender side is
the case of a ballooned guest with enough holes within a batch. These
will trigger 1G allocations before the releasing of memory happens. To
solve this, the releasing of memory has to happen more often, probably
after crossing each 2M boundary.
