Ah, the dangers of cut-n-paste of code you don't understand. Been there, done
that.
I should probably add some (optional?) code to the container stuff to
detect when duplicate entries are inserted.

It is on because the code needs to maintain some information for each row that
is not in the data structure returned by the data_access method. Take a look at
the cache_load routine, and you'll see that it is dealing with 2 containers -
the previous one (that would normally be free'd), and the new one. Various
shennanigans match up rows that are the same and deal with new or missing rows.

You are lost in a twisty maze of little standards, all different.
