I am afraid this is not reflecting reality.
I am pretty sure that "give me that document on a USB stick, and I'll take
a look" leads to using things like libreoffice (or any other editor liked
by general public) to open the file directly on the FAT USB stick. And
that's pretty much guaranteed to use mmap().
