Query: Cohen-Macaulay Loci of modules   The Cohen-Macaulay locus of any finite module over a noetherian local ring
$A$ is studied and it is shown that it is a Zariski-open subset of $\Spec A$ in
certain cases. In this connection, the rings whose formal fibres over certain
prime ideals are Cohen-Macaulay are studied.
