I have a qx.ui.table.model.Simple which has many CellEditors, probably
it is related to them, but currently only filled with a few rows.
In future some 12'000 rows will be entered.

The hash value or a compound key string of both above or, a hashtable of the

hashtable of the second.

On a 8-core 3.4GHz Linux.
