Subject to COW, I presume. Probably in units smaller than the whole
file (per page?)
It can be COW or not, depending on the options passed to mmap.
And yes, it's mapped in units of pages.

Agreed with David. Also,

I partook in that discussion, and I still have no idea why TOML was chosen,
over, say, a defined subset of YAML, or a slightly extended JSON.
But the folks that were highly invested and putting the work in

I had been working on this same problem intermittently for several months,
so thanks, but...
error: Invariant type variable 'AnyStr' used in protocol where
covariant one is expected
is called out

In contrast, a mmap'd file is memory that you do indeed own.

the physical memory pages holding it appear in the address
