WFM. I've renamed "ospageid" to "os_page_num" in 0003, and I've also
renamed "node_id" to "numa_node" in 0002+0003, to make it clearer what
kind of node this is.

This reminds me whether it's fine to have "os_page_num" as int. Should
we make it bigint, perhaps?

Attached is v28, with the commit messages updated, added <warning> about
allocation of the memory, etc. I'll let the CI run the tests on it, and
then will push, unless someone has more comments.
