Linux randomises userspace executables on per-exec (check out /proc/self/maps).

BSD also does the same for userspace, but their new feature is that they randomise the kernel per-boot (by re-linking the objects). This is a far stronger form of kASLR (though I think they're calling it something else because it requires relinking the kernel binary).

Even Windows does this well.

Bragging about boot-time ASLR seems quite odd for an article like this, given that traditional operating systems have had similar (and in many ways superior) features like this for more than a decade (PaX introduced ASLR in Linux in 2001, OpenBSD had it by-default in 2003, and Linux shipped it by-default in 2005).
