I had written that patch when I found a possibility of freezing failure when
looking at the code. I hadn't really hit the problem myself. (And to test my
patch's effectiveness, I had used a synthetic scenario that I had created.)

So, since you seem to have hit the problem during normal usage itself and not
while doing anything fancy, out of curiosity, what triggered the problem?
