Due to a race with collecting events, it looks like some events will still
slip through the crack and we might wind up having missed a transition after
five minutes. If we see that we are already in RELOADING (the state transition
we are looking for) when we would declare the node wedged, then fake the
transition and continue.

I suspect this would not happen if I just looped on event_poll til there
were no more events, but I am afraid of letting that loop go unbounded.
So til I gather more data, lets go with this hack check.
