I don't think I'm wrong here, unless you're leaving something out.

There's a difference between:

	P1003 will not compromise the interface to accomodate
	layered implementations.

And:

	P1003 is for UNIX only.

And I fail to see how an extension that happens to make it easier to
write portable programs that remain reasonably efficient on layered
implementations compromises the interface. Nobody's saying "get rid
of fork()" this time.
