If it were a coding issue, such slowness would be more generally demonstrable.

I'd forgotten that your original report was that it's slow only when the deletion query is one of a sequence of queries executed from a PDO client, not from phpMyAdmin. So it appears to be a PDO issue. Is this with PDO MYSQLND multiqueries?
