Note that the fact that it magically went away certainly implies that
it never "really" existed, and that something was using a pointer or
similar.
IOW, this is not some IO that got scribbled over, or a cache that got
corrupted. If it had been real corruption, I would have expected that
it would have stayed around in memory.
