> * Implement dirty reads or shared row locks and use them in RI triggers
>
> Adding shared locks requires recording the table/rows numbers in a
> shared area, and this could potentially be a large amount of data.
> One idea is to store the table/row numbers in a separate table and set
> a bit on the row indicating looking in this new table is required to
> find any shared row locks.
