What is a "physical page" for this purpose? You want a page whose
size will make sure you don't trigger copy-on-write when you change
some bit -- are you sure that this size is always the same as the
"page size" we use for so-called "page-aligned" allocations?
And if the answer is YES, how future-proof is it?

I don't know whether we are missing something. We are on new ground
here: we never cared in Emacs about physical layout of memory, at
least not so much.
