I agree with Rik that relaxing the ordering here may well result
in very unintuitive behavior. In particular I often write code that
looks like

	MPI_irecv(a,1, MPI_INTEGER, 0, MPI_ANYTAG, MPI_WORLD)
	get_actual_tag
	switch(tag) {
	case tag1:
		MPI_irecv(a,1,MPI_INTEGER, 0, yet_another_tag, MPI_WORLD);
		break;
	...
	}

which presumably wouldn't work properly. This seems to one of the basic
uses of the tag field (to me, at least).
