I wonder if they implemented a copy-on-write fork syscall in NT. Otherwise it will be slower (and use a lot more memory) in some scenarios.

Edit: And cow fork only makes sense if there is memory over-commit. So to be fully featured it would need a separate memory subsystem with memory over-commit.

Looks like it wouldn't be the first copy-on-write fork() on NT; Interix had that already many years ago.

Solaris doesn't have VM over-commit either, and few people would claim it's not a fully featured UNIX.
