If the problem is reproducible, then I think we can try out a few
things to narrow down or get some clue about the problem:
(a) modify function new_cluster_needs_fsm() such that it always
returns true as its first statement.  This will tell us if the code in
that function has some problem.
(b) run with Valgrind
