>Description:
in cgd_modcmd:

        case MODULE_CMD_INIT:
                cgdattach(4);

                return devsw_attach("cgd", &cgd_bdevsw, &bmajor,
                    &cgd_cdevsw, &cmajor);
                break;

        case MODULE_CMD_FINI:
                return devsw_detach(&cgd_bdevsw, &cgd_cdevsw);
                break;

I cannot find where cgdattach() is undone.  If it is done through
a non-obvious hyperspace pointer maneuver, the resource releasing
code is indeed very well hidden.
