/* Do this only after g_main_loop_quit().
*
* This interface was broken (incomplete) since it was introduced.
* ->delete() does cleanup and free most of it, but it does not
* actually remove and destroy the corresponding GSource, so the next
* prepare/check iteratioin would find a corrupt (because partially
* freed) GSource, and segfault.
*
* Apparently one was supposed to store the GSource as returned by
* G_main_add_ll_cluster(), and g_source_destroy() that "by hand".
*
* But no-one ever did this, not even in the old hb code when this was
* introduced.
*
* Note that fsa_cluster_conn was set as an "alias" to cluster->hb_conn
* in do_ha_control() right after crm_cluster_connect(), and only
* happens to still point at that object, because do_ha_control() does
* not reset it to NULL after crm_cluster_disconnect() above does
* reset cluster->hb_conn to NULL.
* Not sure if that's something to cleanup, too.
*
* I'll try to fix this up in heartbeat proper, so ->delete
* will actually remove, and destroy, and unref, and free this thing.
* Doing so after g_main_loop_quit() is valid with both old,
* and eventually fixed heartbeat.
*
* If we introduce the "by hand" destroy/remove/unref,
* this may break again once heartbeat is fixed :-(

*
* B.probe -> B.start
* B.probe -> B.stop
* B.stop -> B.start
* A.stop -> A.start

*
* B.stop -> A.stop

*
* B.probe -> B.stop -> A.stop -> A.start -> B.probe
*
* We could kill the 'B.probe -> B.stop' dependency, but that
* could mean stopping B "too" soon, because B.start must wait
* for the probes to complete.
*
* Another option is to allow it only if A is a non-unique
* clone with clone-max == node-max (since we'll never be
* moving it). However, we could still be stopping one
* instance at the same time as starting another.
* The complexity of checking for allowed conditions combined
