There are two fairly independent parts to improving scrubbing: one is
making it asynchronous and second is improving clear_page() performance.

I would like to clear a bunch of Xen heap pages at once (i.e. not
page-by-page).
Greatly simplifying things, let's say I grab (in common/page_alloc.c)
pg = page_list_remove_head(&heap(node, zone, order)
and then
mfn_t mfn =
_mfn(page_to_mfn(pg));
