This is a great write-up!

Makes me wonder if there is an alternative universe in which there is a syscall with semantics similar to mmap that avoids these pitfalls. It's not like mmap's semantics are the only semantics that we could have for memory-mapped IO.




This would be exactly the kind of innovation we would need in computer science. Instead we often get stuck in local minima (in this case a 40-year old POSIX interface) without realizing how much pain this causes.
