This is complete nonsense. If we think that's a generic problem, we
should be fixing the problem (ie, making the checkpointer smarter);
not expecting that DBAs will monitor their logs for an undocumented
issue. The number of installations where that would actually happen
is epsilon compared to the number where it won't.
