Hi, this patch fixes a bug I've found while debugging a failure reported by Yi Zhang [1]. This patch seems to make that failure disappear [1]. Yet it was tested only together with other debug patches (which add logs and invariant checks), so I don't know whether the other patches influenced the outcome as well. At any rate, this patch does fix a bug.
