What do you mean by "the handler function", and for that matter what do
you define as "each time"? The ExecForeignInsert method certainly ought
to be called once per row inserted, but the same is true of
ExecForeignUpdate and ExecForeignDelete. The setup methods such as
BeginForeignModify should only be called once per query though.
