Also,when a record in a table is updated it is also moved to the bottom of the table.
Only if there's not any free space that could hold the record earlier in
the table. (The free space has to not only exist, but be entered in the
FSM, though, so there are cases where there might be free space
available but the backend doesn't know about it.)

Immediately after insertion of the record.
