What's the length of the key tuples, and are there bounds on the
component ints ? Is the number of ints in the data tuples fixed ? What's
in the subdictionnaries, typically ?  "millions of 5 bit integers" hints
of the possibility of a radical change of representation, but a radical
change of representation can only be devised if we know what's stable
- the task.
