what i've done for now is this (until someone tells me how crazy this is :)

        for (;;) {
                rv = check_ack();
+                rv = 1;
+                printf("HACK! detected that a node was fenced, automatically"
                         "starting cleanup sequence for %s\n", 

                if (rv)

                rv = check_cluster();
                if (rv)
