I don't disagree; just fishing for a commit message. :)

For future reference, here's what POSIX has to say.

	Implementations shall not generate a different error
	number from one required by this volume of
	POSIX.1-2008 for an error condition described in this
	volume of POSIX.1-2008, but may generate additional
	errors unless explicitly disallowed for a particular
	function.

So ENOMEM would have been allowed from that front.
