> The idea of SubjectRegistrationLoginModule while attractive just can't work.  The idea behind subject registration is that we want to compute the AccessControlContext for a subject once and cache it.  That can only be done once the subject is fully populated by all login modules, so if the ACC is determined by a login module it must be the last one.  However, if any previous LM is marked REQUISITE no further modules will be processed.  Therefore we have to register the subjects in some other way.  Just maybe we could "preregister" the subject but determine the ACC lazily??
