- Which UNIX API? (Here we go again. :-)
- Asynchronous I/O.
- Waiting for multiple synchronisation objects.
- ACLs on objects.
- Quotas.

-
- Which new API? POSIX 1003.1, which is a standard and therefore hardly new?
- 1003.1 is an API standard, not a shell standard.

-
- All interactions with the NT kernel go through the object manager, and hence
- through the security subsystem.

-
- NT uses the protected subsystem approach made popular by Mach. OS/2 provides
- a DOS API, but the NT kernel knows nothing about DOS, since DOS (and OS/2, and
- POSIX, and...) APIs are provided by the subsystems.
