They're hardly "duplicates": each event is for a different tuple.
For RI checks, once you get past a certain percentage of the table it'd
be better to throw away all the per-tuple events and do a full-table
verification a la RI_Initial_Check(). I've got no idea about a sane
way to make that happen, though.
