It's not an emulator. The NT kernel really does support the necessary system calls.

  Sure, but there's a layer that emulates the linux syscalls. Though perhaps it's more appropriate to call it "translates" instead of emulate.

    Its not a layer on top of the NT system call infrastructure. Its brand new NT system calls that do exactly what the equivalent Linux ones do. There is no combination of win32 NT system calls that will get you the behavior of fork().

      Aren't the NT system calls also just a personality module above the actual NT kernel? The kernel was originally designed to provide multiple kinds of user spaces so that it could run OS/2 programs alongside Win32 ones.

        No. win32 is a personality, the underlying ntdll calls are not part of that.
