Changelog: v1 - v2 - Removed debugging change to INIT_MEMBLOCK_REGIONS
This fixes a problem with use after free that can happen when there are many physical regions and deferred pages are enabled.
Also, this fix is needed for my upcoming improvements to deferred pages: "complete deferred page initialization", where we do not zero the backing struct page memory.
